RB Leipzig head coach Julian Nagelsmann insisted the club are not nervous about Dayot Upamecano's future amid interest from Bundesliga champions Bayern Munich.

Bayern chairman Karl-Heinz Rummenigge revealed the Bundesliga and Champions League holders are keeping an eye on star Leipzig centre-back Upamecano, with David Alaba set to leave Munich on a free transfer at season's end.

Upamecano – who reportedly has a release clause – has also been linked to the likes of Manchester United, Manchester City, Chelsea and Liverpool following his exploits for last season's Champions League semi-finalists Leipzig.

Nagelsmann responded to Rummenigge's comments and he was bullish regarding the 22-year-old France international's future, after questioning Bayern's public approach.

"It's always clever to get the other team nervous, however we aren't nervous," Nagelsmann told reporters ahead of Saturday's trip to Mainz.

"We know about Upamecano's contract. We know that we want to keep him for longer and that we like to have him with us.

"You can see that, as he's playing every single game for us.  But we also know the mechanisms in football. So if they want to make me or the club nervous, then it hasn't worked.

"But I don't think that this was their main intention. I believe that they said that to get a foot inside the door and make other teams that want to sign him nervous instead. But you have to ask Mr. Rummenigge, why he said what he said."

Nagelsmann added: "It is pretty normal in our business, that if a talented and young player has a buy-out clause other teams are interested in him. To what extent, someone has to then mention that publicly is up to them to assess if it's right or wrong.

"I don't have anything against it. But if it would've been the other way around, they might not have enjoyed it at all. I'm not really bothered by it. As I said already, in our business it is pretty usual. It is a part of it. Sometimes it's only about rumours but sometimes it is more concrete.

"Therefore, it isn't much of a surprise to me. Dayot Upamecano played a lot lately. I have already clarified, that some people tend to forget that he is still very young and still has to take more steps to progress further. But he is clearly capable of going those steps forward. Indeed, he had a couple of unlucky situations on the way forward."

Inter star Lautaro Martinez's future could be closer to being sorted, while Frank Lampard is under enormous pressure.

After impressing at Inter, Martinez, 23, has been strongly linked with a move to Barcelona.

The Argentina international is contracted at Inter until 2023, but that could be set to change.

TOP STORY – INTER OPTIMISTIC OVER MARTINEZ RENEWAL

Inter are optimistic about reaching an agreement for a new contract with Lautaro Martinez, according to Sky Sport.

The report says Martinez's agents met with Inter on Wednesday.

Martinez has scored nine goals in 18 Serie A games this season, having netted 14 in 35 in the league in 2019-20, leading to interest from Barcelona.

ROUND-UP

- As Chelsea's struggles continue, Lampard is under growing pressure as head coach. Sky Sports reports the former England international will lose his job unless results improve immediately. Chelsea have lost five of their past eight Premier League games to slip to eighth in the table. The Independent, meanwhile, reports Chelsea are not interested in an interim replacement. Former Paris Saint-Germain boss Thomas Tuchel, RB Leipzig coach Julian Nagelsmann, Southampton's Ralph Hasenhuttl and ex-Juventus coach Massimiliano Allegri have been linked.

- Previously linked to Arsenal, Houssem Aouar may be looking elsewhere if he leaves Lyon. ESPN claims the midfielder is eager to join Barcelona or Real Madrid.

- Set to stay at Manchester City until the end of the season, Eric Garcia has been linked with a move to Barcelona when his deal expires in June. However, Mundo Deportivo says PSG are planning a move for the defender.

- Arsenal could make moves in January. Sky Sports reports they have approached Real Madrid about a move for Martin Odegaard, while Cuatro claims Sevilla are hoping to loan the midfielder.

RB Leipzig head coach Julian Nagelsmann said football and the NFL can learn from each other as he revealed his admiration for the Green Bay Packers.

Nagelsmann – one of Europe's finest tacticians – said he is a fan of American football after hailing the "extraordinary" discipline of the league's players.

As Aaron Rodgers and the Packers prepare to face Tom Brady's Tampa Bay Buccaneers in the NFC Championship Game on Sunday, Leipzig boss Nagelsmann insisted the two sports can learn from each other.

"Our general manager Timmo Hardung is a huge Green Bay Packers fan, so that's rubbed off on me a bit," Nagelsmann told reporters ahead of Leipzig's match against Union Berlin on Wednesday.

"My heart beats for them a bit, their history is very interesting and different to most of the other clubs in the NFL."

Nagelsmann added: "It's a very interesting sport. And I think we can learn a lot from American football in soccer, and our players can learn a lot from it as well. Especially in terms of their discipline in studying and executing the team's playbook. I definitely think that's an area that soccer can improve on.

"The game is based on an unbelievable number of plays, and the players have to understand a lot of specific terms and then act accordingly out on the field. They have to do all that extremely quickly, which is extraordinary."

"You could see in the games that there were one or two tricks – I'd like to see a bit more of that. 'Hitch and Pitch' I think it's called. That worked quite well in the play-offs a couple of times," he continued.

"So American Football can learn from football, but definitely vice versa too. And if any NFL coaches would like to have a chat about it all, feel free to get in touch!"

Leipzig – Champions League semi-finalists last season – are third and four points adrift of Bundesliga leaders Bayern Munich after 16 matches in 2020-21.

Julian Nagelsmann backed Erling Haaland to get even better after his RB Leipzig team were on the receiving end of a masterclass from the Borussia Dortmund striker. 

Haaland scored twice and had a hand in another goal for Jadon Sancho as Dortmund beat Leipzig 3-1 on Saturday, with Nagelsmann's side missing the opportunity to take top spot in the Bundesliga from Bayern Munich. 

The brace took Haaland's Bundesliga total to 25 goals in 25 matches, of which only 20 have been starts. He has netted with a hugely impressive 34.3 per cent of his shots, too.

BVB's opponents on Saturday were also interested in Haaland when he left Salzburg and coach Nagelsmann acknowledged his latest performance was evidence of why he was so sought after. 

He also pointed to the talent around Haaland in the Dortmund team to explain why it is so difficult to deal with one of Europe's standout stars. 

"Erling we could have defended, but not if the players around him have too much space in a one-against-four situation," Nagelsmann said.

"Of course, he is an exceptional striker - this is why we wanted him, too. Dortmund got him.

"I think he just scored 25 goals in 25 Bundesliga games, something like that. This is truly extraordinary. Unbelievable stats."

Haaland had also scored twice against Leipzig in the sides' meeting at the end of last season.

Nagelsmann added: "This is not the first goal he scored against us. He has some serious quality and is very young.

"So, I think I can't judge him as well as our opponent but he for sure has some potential to develop. He will get even better.

"And the league will have a lot of joy with him. Not the opponents, though."

Julian Nagelsmann has no intention of swapping RB Leipzig for Borussia Dortmund despite being suggested as a permanent successor to Lucien Favre. 

Leipzig boss Nagelsmann is considered one of the most promising coaches in European football and led his team to the Champions League semi-finals last season. 

The 33-year-old, who has a contract at the Red Bull Arena until 2023, has been touted as a candidate to take over Dortmund next season, with Edin Terzic having replaced Favre on an interim basis in December. 

However, Nagelsmann insists there is no need for anyone associated with Leipzig to worry about what the future holds because he intends to stay put. 

"There is no reason to be tense regarding Dortmund," Nagelsmann said ahead of a Bundesliga meeting with BVB on Saturday. 

"The situation with Dortmund has remained the same as it was during my time as Hoffenheim coach. There was and there is no match. 

"I am comfortable and I have big targets to achieve with Leipzig. As I said, there is no reason for anyone at RB Leipzig to get nervous regarding Dortmund."

Leipzig sit second in the Bundesliga table, six points ahead of fourth-placed Dortmund and two adrift of leaders Bayern Munich. 

Asked about Nagelsmann during a pre-match news conference on Thursday, BVB sporting director Michael Zorc said: "Despite his age, Julian has had a remarkable managerial career. With Hoffenheim, he was able to work sensationally well, now he's having a just as sensational season with Leipzig. 

"I believe, it is undisputed that he's a complete football expert. He always implements innovation into his coaching technique. He is always able to get his team to work well. 

"We need to try to fight against that on Saturday. We already came up against each other a few times and it's not like we had no success at all in these match-ups. 

"I see ourselves, also due to the position in the table, in the role of the hunter. We want to minimise the gap between us and to the top of the table."
