Robert Lewandowski scored a stunning goal and Serge Gnabry also got on the scoresheet against his former club as Bayern Munich beat Hoffenheim 4-0 on Sunday.

Julian Nagelsmann's side were threatening from the off and Gnabry lashed in from an acute angle after making a good run into space in the box, but free-scoring striker Lewandowski stole the show, bending a powerful effort high into the net from long range to leave Hoffenheim goalkeeper Oliver Baumann with no chance.

Substitutes Eric Choupo-Moting and Kingsley Coman made the scoreline comfortable late on as the visitors succumbed to Bayern's relentless pressure.

The result keeps Bayern top of the Bundesliga, one point ahead of title rivals Borussia Dortmund with nine games played.

Lewandowski and Gnabry both came close to opening the scoring inside the first eight minutes, with the former dinking just wide from seven yards and the latter finding the net but seeing it disallowed following a VAR check due to a foul from Jamal Musiala in the build-up.

Not to be denied, Gnabry rifled a low shot into the bottom-left corner from a tight angle on the right in the 16th minute after being found by Musiala and Lewandowski unleashed a ferocious strike into the top-right corner from outside the box on the half-hour mark after good work from Thomas Muller. 

Bayern had several more good chances at 2-0 up, but did not find the net again until Andrej Kramaric's poor clearance ricocheted off the back of Dayot Upamecano and into the path of substitute Choupo-Moting, who slotted home in the 82nd minute.

Fellow Bayern substitute Coman added further gloss to the scoreline five minutes later, racing onto a long ball in behind and lashing emphatically past Baumann to make it 4-0.

Gianluigi Donnarumma's move to Paris Saint-Germain dominated headlines following a busy off-season in the French capital.

Donnarumma was part of an incredible transfer window for PSG, which included the likes of Lionel Messi and Achraf Hakimi arriving.

But Donnarumma is already reportedly considering his future with the Ligue 1 giants.

TOP STORY – DONNARUMMA WEIGHING UP FUTURE

Gianluigi Donnarumma will leave Paris Saint-Germain if he continues to be overlooked in favour of Keylor Navas, according to Calciomercato.

Donnarumma only joined PSG from Milan on a free transfer at the start of the season, but he has found himself playing second fiddle to Navas in Paris.

The Italy international has already been linked with Juventus and Barcelona.

ROUND-UP

- Luis Suarez is seeking a new contract at Atletico Madrid but the LaLiga champions want to hold off until the end of the season before deciding, per Saturday's Marca. Atletico have been linked with wantaway Fiorentina star Dusan Vlahovic. Manchester City, Tottenham, Arsenal and Inter have also been linked to Vlahovic.

- Bayern Munich are pushing to sign Salzburg forward Karim Adeyemi, reports Sport1. The 19-year-old has impressed in Austria, where he has been linked with Liverpool, Borussia Dortmund, Atletico Madrid, Inter and Real Madrid.

- Porto's Luis Diaz is attracting interest from Newcastle United, Chelsea, Bayern and Madrid, claims Nicolo Schira.

- Antonio Rudiger's priority is to stay at Chelsea but Fabrizio Romano says the race is open to sign the Germany defender, with Madrid and Bayern among his admirers.

- Mundo Deportivo claims Inter midfielder Marcelo Brozovic has emerged as an option for Atletico, who are planning for life without Saul. Brozovic has been linked with Manchester United and Barca.

Julian Nagelsmann has set up a kitchen control room to guide Bayern Munich while he remains away from the team after a COVID-19 positive test.

Assistant head coach Dino Toppmoller will lead from the touchline when Bayern host Hoffenheim in the Bundesliga on Saturday, having also stood in for the 4-0 win at Benfica in the Champions League on Wednesday.

Despite being fully vaccinated, Nagelsmann learned that the flu-like symptoms he was experiencing in Portugal were caused by coronavirus.

He said he feels "a bit weak" and is wary of getting in the way of the work being carried out by Toppmoller and fellow assistant Xaver Zembrod.

"Still, I am trying to take control if possible," said head coach Nagelsmann.

"In isolation, I have built myself a little analysis centre with a big screen, iPad and laptop. I have different technical abilities now, also when it comes to the scouting feed for the game.

"It looks like a big data centre, right in my kitchen so that I have a short way to the tea kettle. I am positive that we will have a good impact. For training rhythm, this is not so bad because we don't really have training right now."

With such a heavy game schedule, Bayern's players are only ticking over between matches, rather than going through major sessions on the training pitch.

Nagelsmann is optimistic of being back at his Bayern desk in a matter of days, and says his positive test came as a jolt, insisting he had been trying to stay out of danger.

"I think we are all being cautious basically. This is hard, you cannot always say 100 per cent where you get the infection from," Nagelsmann said.

"I haven't done anything illegal or been at this party in Berlin where you had 22 people positive. I wasn't there, as an example. Basically, you never know. I was also a bit shocked.

"I just thought that I had a flu like many people at that time. For vaccinated people like me, things get less restricted and then you can also get infected easier.

"Of course, I went to a restaurant last week but I don't know... I couldn't find out where I got it from. I don't think you can, this is really hard. The virus you have in your body doesn't come with a number that makes it trackable. That's just how it is."

Bayern head into the weekend with a one-point advantage over Borussia Dortmund at the top of the Bundesliga, winning six and losing just one of their first eight games as they seek a 10th consecutive league title.

Nagelsmann is in his first season with the club, having left RB Leipzig at the end of last season to take over from Hansi Flick, who left Bayern to become head coach of Germany.

Before Leipzig, Nagelsmann cut his teeth with Hoffenheim, so he misses out on a reunion on Saturday.

Between 2016 and 2019, Nagelsmann managed Hoffenheim in 116 Bundesliga games, achieving a points-per-game average of 1.65, comfortably the best record of any coach of the club to have taken charge of at least five top-flight games.

On Saturday, Bayern will be looking to avoid a second successive home defeat in the Bundesliga, having been beaten 2-1 by Eintracht Frankfurt in their previous game at the Allianz Arena. The last time they lost consecutive league home games was in 2001 under Ottmar Hitzfeld.

Superstar 22-year-old Kylian Mbappe is expected to leave Paris Saint-Germain at the end of this season.

Real Madrid have long courted the France international and are expected to secure his signature.

PSG remain hopeful of Mbappe extending his contract but there could be another twist in the transfer saga.

Madrid's LaLiga rivals Barcelona appear ready to make a surprise move.

TOP STORY – BARCELONA READY FOR MBAPPE MOVE

Barcelona believe they can outspend Madrid and land Mbappe from PSG, according to AS.

Despite their financial challenges, the Catalans intend to hijack their rivals' move for Mbappe, who will be a free agent in mid-2022.

Barcelona's salary cap will increase by then and vice president Eduard Romeu reportedly wants to make one major signing.

ROUND-UP

Bayern Munich head coach Julian Nagelsmann has tested positive for COVID-19.

Nagelsmann was absent due to 'flu-like symptoms' as Bayern beat Benfica 4-0 in Portugal on Wednesday, maintaining their flawless Champions League group-stage record so far this season, with assistant manager Dino Toppmoller standing in.

The Bavarian giants have won each of their first three games in the competition, scoring 12 times and not conceding a single goal to sit five points clear at the top of Group E.

The club confirmed on Thursday morning that the 34-year-old, despite being fully vaccinated, had tested positive for the virus and will return to Munich separately instead of with the rest of the squad before isolating at his home.

As a result, Nagelsmann will miss Bayern's next league game at home against Hoffenheim on October 23, with Toppmoller set to continue filling in.

Bayern are one point ahead of Borussia Dortmund at the top of the Bundesliga, winning six and losing just one of their first eight games as they seek a 10th consecutive league title.

Raheem Sterling is open about a move away from Manchester City for more game time.

The 26-year-old dropped down the pecking order at City last season before an excellent Euro 2020 campaign, where he scored three times for runners-up England.

Sterling has only managed five starts in all competitions this season and could be on the move in the January transfer window.

TOP STORY – BARCELONA PRIORITISE STERLING MOVE

Barcelona will make completing a loan deal for Manchester City winger Raheem Sterling their priority in January, claims Sport.

Sterling faces strong competition for places at City and has spoken publicly about his desire for more time on the field.

The Catalans have financial restraints inhibiting their transfer activity but view a loan deal for the England international as an attractive option given their ambition.

ROUND-UP

- Manchester City are keeping a close eye on Fiorentina striker Dusan Vlahovic as the race for his signature hots up, according to Tuttosport. City are short on forward options, having not replaced Sergio Aguero following his exit for Barcelona.

- Calciomercato reports that Inter are concerned about the state of contract talks with Croatia international Marcelo Brozovic,  whose current contract expires in June.

Bayern Munich defender Dayot Upamecano said Robert Lewandowski and Real Madrid star Karim Benzema are both worthy of this year's Ballon d'Or.

Lewandowski and Benzema are among the nominees for football's most prestigious individual award – the 30-man shortlist will be whittled down to just three players.

Upamecano is team-mates with Lewandowski at Bundesliga champions Bayern, while he also plays alongside Benzema for World Cup and Nations League holders France.

Asked about Lewandowski and Benzema ahead of Bayern's Champions League fixture with Benfica on Wednesday, Upamecano replied: "Very good question!

"Lewandowski or Benzema, both of them deserve it [Ballon d'Or]. They are the two best strikers in the world. They prove it year after year.

"If Lewandowski wins, I would be very happy for him because he is my team-mate at Bayern. If Benzema wins, I also would be very happy for him."

Prior to Madrid's 5-0 rout of Shakhtar Donetsk on Tuesday, Benzema had been involved in more shot-ending sequences of play (76) than any other player in the Champions League.

In this same period, Lionel Messi (12) was the only player who had recorded more multi-shot involvements than Benzema (10), which captures all instances of sequences where a player is both involved in the build-up and takes the shot.

Meanwhile, Lewandowski has scored five goals in six Champions League appearances against Portuguese opponents, including three against Benfica – no player has ever scored more times against sides from Portugal in the competition.

Bayern are on a record unbeaten run of 19 matches away from home in Champions League (W15 D4), netting 54 goals during this streak since losing 3-0 at Paris Saint-Germain in September 2017. Over a third of their goals in this unbeaten run have been scored by their Lewandowski (19 – 35 per cent).

German giants Bayern's eight unbeaten matches against Benfica in the European Cup/Champions League (W5 D3) is the joint-most by a team against an opponent since the tournament began in 1955 – Bayern versus Spartak Moscow (W5 D3) and Barcelona versus Lyon (W5 D3) have also faced eight times without ever losing.

Since the start of last season, Bayern have averaged more goals (3.2) and have a higher expected goals tally (2.6) per game than any other team in the Champions League. Among teams involved in both the 2020-21 and 2021-22 tournaments, they also have the highest shot conversion rate in this period (18.3 per cent).

Erling Haaland is the name on everyone's lips.

He has starred for club and country, but Real Sociedad's Swedish forward Aleksandar Isak has also impressed.

Isak could be lured to Barcelona if Haaland is not available.

TOP STORY – ISAK WANTED AT CAMP NOU

Barcelona are lining up a move for Real Sociedad forward Alexander Isak if they are unable to sign in-demand Borussia Dortmund star Erling Haaland, according to Diario AS.

Haaland is wanted by Barca and Europe's elite, with the Norwegian linked with Real Madrid, Manchester City, Bayern Munich, Manchester United, Liverpool, Juventus and Paris Saint-Germain.

With competition fierce, LaLiga outfit Barca are looking close to home and at Isak as an alternative.

ROUND-UP

- Ekrem Konur claims City are considering Barca sensation Ansu Fati as a possible replacement for Raheem Sterling should the England international depart the Premier League champions. Barca are reportedly interested in Sterling on a loan deal.

- Dortmund want Ajax's Sebastien Haller to succeed Haaland at the Bundesliga outfit, reports Calciomercato. Former Eintracht Frankfurt forward Haller has starred for the Eredivisie giants.

- Juve's objective is to sign Monaco and France star Aurelien Tchouameni, says Calciomercato. Tchouameni is also a target for United, City, Chelsea, Liverpool, PSG and Madrid.

- Gazzetta dello Sport claims Juve, Milan and Tottenham are eyeing PSG's Mauro Icardi.

Julian Nagelsmann was pleased with Bayern Munich's display in their 5-1 thrashing of Bayer Leverkusen but felt his side should have added even more goals to their tally.

The reigning champions responded to their first defeat of Nagelsmann's tenure two weeks ago against Eintracht Frankfurt with a superb attacking display at BayArena on Sunday.

Robert Lewandowski and Serge Gnabry each scored a first-half double and Thomas Muller was also on target in between those braces, all in the space of 37 minutes.

It marked the first time Bayern have scored five goals away from home in the first half of a Bundesliga match as they reclaimed top spot from Borussia Dortmund.

Bayern also hit the post through Leroy Sane, whose eight shots was the most of any player in a game this campaign in the German top flight.

And with Patrik Schick getting a consolation for Leverkusen in the second half, Nagelsmann does not believe the scoreline was a true reflection come full-time.

"We had an incredible number of closing situations and an outstanding structure," he told DAZN. 

"It sounds strange at 5-0, but we also had a chance of scoring sixth, seventh and eighth goals in the first half. We could have scored more.

"The second half was more calm and that's completely normal from both teams' point of view. 

"A lot of things we didn't do well against Frankfurt worked out today. In the end we are very happy to win the game."

Only twice before in Bundesliga history has an away side scored five goals in a quicker time from kick-off – Dortmund against Schalke (23 minutes) and Karlsruhe versus Frankfurt (30 minutes), both in 1964.

There have been 10 occasions when teams have scored five or more goals in the first half of a Bundesliga game this century, with Bayern responsible for six of those 45-minute thrashings, including when they put five past Dortmund before the break in March 2018 on the way to a 6-0 win.

Leverkusen are no strangers to one-sided first halves, meanwhile, as they are the only team to have scored six goals in the opening 45 minutes of a match in the division since the turn of the millennium, doing so in their 6-1 win over Frankfurt in 2018-19.

"It was a terrible beginning," Leverkusen goalkeeper Lukas Hradecky added. "We have to ask ourselves whether we gave it our all. There was something missing from everyone today."

Lewandowski's two goals came from three shots as the Poland international brought an end to his mini drought.

His run of scoring in 15 successive league games was ended prior to the international break when failing to net against Greuther Furth and then Frankfurt, before also going scoreless in Poland's double-header of October fixtures.

The 33-year-old has now scored two or more goals in 73 different Bundesliga games – a tally bettered only by late Bayern great Gerd Muller (87) – and was happy to joke about his short-lived scoreless run after getting back on the scoresheet.

"Four games without a goal... which four games? Do you mean training? I scored in the Champions League game before the Frankfurt match," Lewandowski pointed out.

"Personally, I'm happy when people ask when I'll score my next goal. That shows what expectations they have of me.

"Sometimes there are phases when the ball doesn't fall to you, you have to be patient. Today it worked out twice.

"We scored five goals in 45 minutes. At the break it was clear we would take all three points with us to Munich. We can be satisfied with the performance."

The 29 goals scored by Bayern in their opening eight Bundesliga matches equals their previous highest tally at this stage in a campaign from the 1976-77 season.

Bayern Munich helped themselves to five first-half goals as they thumped Bayer Leverkusen 5-1 on Sunday to return to the top of the Bundesliga.

The reigning champions suffered their first defeat of Julian Nagelsmann's tenure last time out, but they responded in the best way imaginable at BayArena.

Robert Lewandowski and Serge Gnabry helped themselves to a couple of goals each in a one-way first half, with Thomas Muller registering in between those doubles.

Leverkusen were level on points with Bayern before kick-off and pulled one back through Patrik Schick, but Nagelsmann's side were able to cruise through the rest of the match to overtake Borussia Dortmund at the summit.

The hosts had won their previous five matches in all competitions, keeping a clean sheet in the last three of those, but it took Lewandowski just three minutes to backheel Dayot Upamecano's centre past Lukas Hradecky.

Bayern went on to lose after opening the scoring against Frankfurt, but there was no sign of that happening against Leverkusen. Shortly after Leroy Sane sent a shot against the right post, Lewandowski lashed home a second of the game on the half-hour.

That was the first of four goals in seven minutes, with Muller in the right place to deflect in a Niklas Sule shot before setting up Gnabry to score. Gnabry then joined Lewandowski in bagging a brace with a shot into the bottom-left corner.

The visitors had kept a clean sheet in only one of their last nine league games, however, and that poor defensive record was extended when Schick latched onto Florian Wirtz's throughball and arrowed a shot past Manuel Neuer in the 55th minute.

Sane squandered a couple of good opportunities to get in on the act, including a header over the bar from close range, while a disallowed Lucas Alario goal for offside was the closest Leverkusen went to further reducing the deficit.

Bayern Munich became the third-fastest side in Bundesliga history to score five goals in an away match as they raced into a 5-0 lead against Bayer Leverkusen inside 37 minutes.

The reigning champions tasted their first defeat of Julian Nagelsmann's tenure at home to Eintracht Frankfurt prior to the international break, but they responded in style at BayArena.

After going back-to-back league games without scoring for the first time in two years, Robert Lewandowski flicked Bayern into the lead inside three minutes in Sunday's match.

Lewandowski scored a second on the half-hour mark and Thomas Muller was next on the scoresheet four minutes later.

Serge Gnabry added a quickfire brace of his own, the Germany international dinking in Bayern's fourth of the contest before slotting in number five two minutes later.

Only twice before in Bundesliga history has an away side scored five goals in a quicker time from kick-off – Borussia Dortmund against Schalke (23 minutes) and Karlsruhe versus Frankfurt (30 minutes), both in 1964.

There have been 10 occasions when teams have scored five or more goals in the first half of a Bundesliga game this century, with Bayern responsible for six of those 45-minute thrashings, including when they put five past Dortmund before the break in March 2018 on the way to a 6-0 win.

Leverkusen are no strangers to one-sided first halves, meanwhile, as they are the only team to have scored six goals in the opening 45 minutes of a match in the division since the turn of the millennium, doing so in their 6-1 win over Eintracht Frankfurt in 2018-19.

Erling Haaland is putting early-season pressure on Robert Lewandowski in the Bundesliga goal charts, with the Norwegian hailed as "massively important" to Borussia Dortmund after his latest heroics.

Bayern striker Lewandowski has finished as the German top flight's leading scorer in six of the last eight seasons, including each of the last four campaigns.

In 2020-21, Lewandowski hit 41 goals to break Gerd Muller's long-standing record of 40 in a Bundesliga campaign, yet it is no foregone conclusion that he will be top of the pile this term.

Haaland is the rising force, and the 21-year-old returned from a thigh injury lay-off to score twice in Saturday's 3-1 victory over Mainz.

The double – a penalty followed by a stoppage-time clincher – took Haaland to nine goals in six Bundesliga games this season, lifting him two clear of 33-year-old Ballon d'Or contender Lewandowski.

It was the fourth time this season in the Bundesliga that Haaland has scored twice in a game, and the 17th double of his league career with Dortmund, which only began in January of last year. He also has a Bundesliga hat-trick and a four-goal game on his Dortmund resume.

In all, Haaland has 49 goals in 49 Bundesliga games for BVB, a startling return and one that has drawn attention from the likes of Real Madrid, Barcelona and Manchester City.

Marco Reus, who scored Dortmund's opener against Mainz, said: "We have obviously missed Erling in the past few games. Today, we have seen it again: he is massively important for us because he always occupies two or three players. The fact that he scored two goals on his comeback is fantastic. That's why we signed him."

Head coach Marco Rose said, quoted on the club's website: "We needed him, including for defending set-pieces. He defended well towards the end. And then he went and scored another goal in the 95th minute. That came in handy."

Whether Haaland stays at the top of the scoring chart remains to be seen. Bayern were in action against Bayer Leverkusen on Sunday, with Lewandowski looking to end what for him represented a worryingly long lean patch: two Bundesliga games without a goal.

Dortmund sat top of the table ahead of that game, and would stay there in the event of a draw. Should either team win at the BayArena, however, they would displace Rose's side from first place.

The race is on to sign Borussia Dortmund forward Erling Haaland, who might be set to make a move in mid-2022.

Real Madrid, Barcelona, Manchester City, Chelsea and Paris Saint-Germain are all interested in the Norwegian goal machine, but could Newcastle United also be a factor?.

Haaland netted 41 goals from 41 games last term for Dortmund and already has 13 this season.

TOP STORY – NEWCASTLE ENTER HAALAND RACE

Newcastle are the latest club to enter the race to sign Borussia Dortmund's Norwegian striker Erling Haaland, reports AS.

The report claims Real Madrid are losing their grip as favourites to sign Haaland, with Manchester City, Paris Saint-Germain and now Newcastle potentially in contention.

The Magpies' move is said to be "not out of the question" following the club's takeover by the Saudi Arabian Public Investment Fund who appear set to make a splash in the transfer market in January. 

ROUND-UP

- Mohamed Salah's agent has arrived in England for contract talks with Liverpool over a £500k-per-week deal, according to the Mirror.

- ESPN reports that Premier League trio Manchester United, Manchester City and Liverpool are tracking Monaco midfielder Aurelien Tchouameni, rivalling Real Madrid. United's interest is said to be based around whether Paul Pogba departs.

- Dusan Vlahovic will follow Federico Chiesa's lead and reject a new Fiorentina contract offer in favour of a move to Juventus, ignoring Premier League interest from Tottenham and Liverpool, reports La Gazzetta dello Sport.

- Barcelona are interested in Manchester United's Nemanja Matic, claims The Sun. The Serbian has a little over 18 months remaining on his United deal so Barca believe they could sign him next off-season on a cut-price deal.

- Goal Germany reports that Bayern Munich are making a move to sign Salzburg talent Karim Adeyemi, with the player's agent and father reportedly holding talks with the Bavarian club on Saturday.

"If you have the ambition and quality, we count on you and give you the chance to develop. With development, there is also performance. That's why it's a great story for Florian but also for us as a club," Simon Rolfes told Stats Perform.

Bayer Leverkusen had money to splash after Chelsea paid a club-record fee to prise German star Kai Havertz from BayArena at the start of 2020-21. His absence was supposed to leave a glaring hole in North Rhine-Westphalia and prompt a frantic search in the transfer market.

But sporting director Rolfes and Leverkusen had other ideas. Rather than use the money recouped in the blockbuster Havertz transfer, Die Werkself opted to look in their own backyard for a replacement – 18-year-old teenage sensation Florian Wirtz.

Leverkusen's faith in youth and their clearly defined philosophy has served them well previously, and they're being rewarded once again by the club's latest wonderkid, who has put Havertz well and truly in the rear-view mirror as Europe's elite queue for his signature.

At home in the number 10 role behind a striker or even as a deep-lying playmaker, Wirtz can do it all on the pitch – as next opponents Bayern Munich may find out on Sunday.

Leverkusen prised Wirtz from Cologne in 2020. Dubbed "the best midfielder to come through the club in 30 years" by local newspaper Kolner Express, Bayern, Borussia Dortmund, RB Leipzig and Liverpool were all circling after Wirtz captained boyhood team Cologne to Under-17 German Championship glory in 2019, but Leverkusen eventually won the race.

Rolfes had first watched Wirtz at the age of 13. He was immediately mesmerised by the Brauweiler-born sensation, who has firmly established himself in the Leverkusen XI, quickly becoming the new face of Die Werkself.

From his junior days, Wirtz has been great at exploiting gaps and creating space in midfield while churning out goalscoring chances with his devastating awareness. Not to mention his defence-splitting passing ability. Five years on and nothing has changed on the international stage.

"Extraordinary player," Rolfes told Stats Perform prior to the international break, after which Leverkusen now prepare to face champions Bayern in a top-of-the-table Bundesliga clash. "I saw him the first time when he was 13 and followed him all the time. Spoke with him before he moved to us, with the parents a lot of times and tried to convince them that it was the right step to come to us and accelerate his development. I and the whole club are very happy that he is with us. That's the interesting thing, I watched him the first time at 13 and he is still playing the same. 14,15, 16, always in that kind of style."

When a player breaks a record held by Havertz at Leverkusen, it is a sign to sit up and take notice.

Wirtz was swiftly thrust into the first team, becoming Leverkusen's youngest-ever debutant at the age of 17 years and 16 days, eclipsing Havertz's record, in last season's 4-1 rout of Werder Bremen in 2019-20. After a handful of appearances in the coronavirus-hit campaign, Wirtz played 29 Bundesliga games, which yielded five goals and as many assists in the post-Havertz era in 2020-21. In February 2021, Wirtz became the first player in the league's history to score five goals before celebrating his 18th birthday.

So, when it comes to comparing Wirtz to Havertz through their first 42 Bundesliga appearances with Leverkusen, how do they stack up against each other?

Wirtz has an equal split between goals and assists (10 each), averaging his 20 goal involvements once every 148 minutes across his top-flight career so far. That's quicker than Havertz managed at the same stage of his Bundesliga career, with his 16 goal involvements in his first 42 apps coming at an average of 165 minutes.

Wirtz also proved a shade more productive in front of goal, with an expected goals per 90 average of 0.16 compared to Havertz's 0.14, but the now-Chelsea forward was able to get more involved in the average game with 65 touches per 90 compared to Wirtz's 58 per 90.

"I wouldn't say they're similar. They're for sure similar in terms of extraordinary qualities and potential for really big careers," Rolfes said. "I would say at the end, Kai plays a little bit more forward and is very good in going deep with a lot of speed. Sometimes it doesn’t look like it because he is so tall but he is incredibly fast. Very direct, fantastic shot with his left foot and a good header. With his height, a very good header of the ball.

"With Florian, I think from a positional sense he is a little bit deeper. More technique in small spaces I would say. Kai likes to use his speed. They are quite different. They unfortunately only played/trained half a year together. It would be nice to have them both together in the squad at the moment because one right foot, one left. They would fit very good together."

With so much attention from a very young age, it is easy for some players to get swept up amid the hype and interest. Not Wirtz.

Wirtz has continued to shatter records and dazzle in the Bundesliga. Against Mainz on matchday six of this season, the Germany international became the youngest player to score 10 goals in Germany’s top-flight, doing so 208 days younger than Lukas Podolski (18 years, 353 days for Cologne in 2004).

No player in the Bundesliga this season has more assists than Wirtz (five) through seven rounds.

With four league goals in just six appearances, he is already only one goal shy of matching last season's haul, despite an expected goals (xG) goal value of 1.0 – no other player has such a large difference between his goals and expected goals.

His nine goal involvements in this season's Bundesliga are only surpassed by Dortmund star Erling Haaland (10), while Wirtz has the best shot conversion rate (36.4 per cent) among all players with at least three goals in 2021-22.

As Wirtz goes from prospect to genuine star, it all comes down to his mindset.

"The attitude is very good. With players and we could see it with Kai Havertz, they know their quality. They are 18 and self-confident because they know about their quality. Special players have that – they can feel that, feel it directly on the pitch. Playing with other good players, they're able to handle it and adapt to the different speed of the game," said Rolfes.

"In that case, they are quite far [developed] and they know there's interest in them because also with 14, 15, 16 it's normal big clubs watched him play. With Florian and Kai, it's quite the same. They always know they’re interesting and extraordinary players."

In all competitions in 2021-22, Wirtz (11) is the only player in Europe's big-five leagues 18 or younger to be involved in seven or more goals, having already found the back of the net twice in the Europa League.

Wirtz has been involved in a goal across all competitions every 47 minutes so far this term – at least up until the international break, it was the best rate of all players in Europe's top five leagues with at least 500 minutes, ahead of Haaland (51 mins), Real Madrid's Karim Benzema (52 mins), Bayern talisman Robert Lewandowski (60 mins) and Liverpool star Mohamed Salah (65 mins).

"In the youth teams, the difference in the quality between him and others was much higher. The game in the youth is around them. Now, he also has a big influence on the game, but he has to position himself better to get the ball and use his quality. Players with extraordinary quality have the ability to find the right spaces but in professional teams they have to wait a little bit in their position and then use their quality," former Leverkusen midfielder Rolfes said. "Compared to the youth where they are doing everything."

It's a frightening thought when you remember Wirtz only celebrated his 18th birthday in May and consider how much growth there is to come from Leverkusen’s prized asset.

Despite being so young, Wirtz is already important in Leverkusen's attacking production – he's been involved in 26 open-play attacking sequences in the Bundesliga this season, with only two players at the club involved in more. Of those 26, 12 have come as the creator of the chance, which is more than any Leverkusen team-mate.

"He will improve year by year. Although he already has a high level. His biggest strength and you could see that in all the years in the youth team, is that he gives his best in each game," added Rolfes. "Doesn't matter where he was playing or which team-mates he was playing with. The first team, U19, U13 etc, he was always giving his best. That is a key element in his development that he is able to adapt at higher levels but he has ambition to always improve and you have to improve.

"Sometimes improvement is also a little bit about changing your game. For sure the opponents want to defend him and watch him, so improvement is sometimes changing a little bit. I'm totally convinced he will have a great career because he has the right mindset to develop. If he keeps that, he is 18 and young, it's a really young guy and he has strengthen his personality etc – that’s normal. We all know how we've been at 18 but if he keeps his mindset and development, he will have a fantastic career."
