Oliver Kahn believed Bayern Munich's hopes of trophy success this season and in the next campaign were under threat with Julian Nagelsmann at the helm.

The tacit admission that the 10-in-a-row Bundesliga champions would surrender their crown if Nagelsmann stayed in charge came in a press conference on Saturday.

Bayern CEO Kahn sacked Nagelsmann and has brought Thomas Tuchel to the club as head coach, with their hopes of a treble remaining alive going into the closing weeks of the season.

The shock departure of Nagelsmann, less than two years after he was acquired at great expense from RB Leipzig, was one the Bayern hierarchy decided was essential.

"The last few days have been hard for us all," Kahn said. "They certainly weren't easy days, and it's safe to assume there was the odd night where I didn't sleep well.

"That's one side of this job that is no longer fun but unfortunately is part of the business. When you let a head coach go, ultimately there's a person behind that decision.

"Nothing big changed, we all see him as an excellent and very good head coach, and on a personal level we understood each other over the course of the last year and three quarters.

"But it's our responsibility and duty to sort out the sporting success of this club, and so we asked ourselves the question of what's the reason behind the big changes in performance.

"So, this isn't a panic decision. It's got nothing to do with panic. We had a close look at everything, and we took the emotions out of the decisions."

Bayern were beaten 2-1 by Bayer Leverkusen last Sunday and as a result relinquished top spot in the Bundesliga to Borussia Dortmund. Dortmund are Bayern's next opponents, and incoming boss Tuchel is a former Dortmund coach.

A beaming Tuchel was presented by Bayern on Saturday, having been first contacted on Tuesday.

"We might have taken the decision on Monday, but we took a chance to look at everything," Kahn said. "It's all about finding out where these big swings in performances come from."

Kahn pointed to last season's Champions League exit at the hands of Villarreal and a 5-0 DFB-Pokal loss to Borussia Monchengladbach in October 2021.

"The fact is there were vulnerabilities that were hard to understand that kept raising their head over several games, despite the fact we strengthened the squad before the start of the season and have one of best squads in Europe," Kahn said.

"The continuity in performance of the team never really got better.

"If you look at the start of the second half of the season, we were often not happy with the performances.

"It's the expectation for a club like Bayern that we are a stable ship, so we started with three 1-1 draws in a row – a tough start to the second half of the season – and you see where we are today. Out of 10 Bundesliga games, we have five wins and three draws. That's not where our expectation levels are.

"That's ultimately why we had to make a decision. The expectations are always at their highest here at Bayern.

"We saw and felt our season targets for this season and next season were in danger, and that's why we came to the decision to let Julian Nagelsmann go. It was a well thought through process, certainly not an emotional decision down to one game."

Kahn said he and sporting director Hasan Salihamidzic had supported Nagelsmann until reaching this decision.

They took no satisfaction in parting company with the 35-year-old Nagelsmann, who will be eager in his next job to prove Bayern made a rash choice.

"Of course, there are nicer things in life," Kahn said. "It was frustrating and he was trying to understand. We explained it as we have explained it today.

"He took it on board and understood. The bottom line is it really did not go how we expected things to go."

Kahn said his open-door policy to the club's players had provided some insight into the vibe of the squad under Nagelsmann's leadership.

"I let players come into my office, have a coffee and listen in," he said. "I think this is one of the strengths of the club. I think everyone had a very clear picture of how the players were feeling and what kind of situation they found themselves in."

Chelsea are assessing Reece James after he withdrew from the England squad for Sunday's Euro 2024 qualifier against Ukraine.

James' season has been ravaged by injury, limiting him to only 18 appearances for the Blues in all competitions.

A knee problem caused the right-back to miss the World Cup in Qatar, along with Chelsea team-mate Ben Chilwell.

James made his England return on Thursday, appearing from the bench for the final five minutes of a 2-1 qualifying win at Italy, only to suffer another setback.

"Reece James has withdrawn from the England squad and will not feature against Ukraine on Sunday," an England statement read.

"The full-back has returned to Chelsea for assessment on an ongoing issue.

"No replacements are planned as Gareth Southgate's squad, including the suspended Luke Shaw, continue their preparations at Tottenham Hotspur Training Ground."

England have Kyle Walker and Kieran Trippier in their squad, but James' latest injury concern is perhaps a bigger blow to Chelsea.

Graham Potter's side resume their campaign on April 1 against Aston Villa, the first of three Premier League matches before their Champions League tie with Real Madrid.

European glory is Chelsea's only realistic remaining aim this season, sitting 10th in the league with 11 games to play.

Kolo Toure has urged Arsenal to learn from past mistakes and hand Bukayo Saka a 10-year contract.

Saka is playing a big part in the Gunners' quest to win the Premier League title, scoring 12 goals and providing 10 assists in the top flight this season.

The winger also made his mark for England in the World Cup in Qatar last year, finding the back of the net three times and posing a huge threat.

Saka is only under contract with the Premier League leaders until the end of next season, but is reportedly on the verge of signing a new deal.

Former Arsenal centre-back Toure wants Saka to be tied down for a decade.

He told Sky Sports News: "One thing I have to say - my advice to Arsenal is for Bukayo Saka to sign for 10 years!

"One mistake that Arsenal made down the years, they had key players that loved the club and they let them go.

"You must keep those players because these players are the players that are going to lead the team for you.

"These are the players you can rely on; these are the players that when it's tough they will put their bodies on the line because they love the club.

"You have two types of players, players that love the club and players who just come and go. You need players who love the club because these are players who are going to fight with their heart."

Toure also expressed his admiration for Arsenal head coach Mikel Arteta but warned the leaders must maintain the high standards they have set in order to fend off Manchester City in the title race.

"He's (Arteta) been incredible. What he is doing as a young manager is inspiring us. You can see the energy he is bringing," Toure, who was sacked by Wigan Athletic in January after a short spell in charge, said.

"He was really lucky to work with one of the best managers in the world in Pep Guardiola - learning from him was vital.

"But with Man City, they have the experience and Arsenal have to be really careful they don't slip because this Man City team will give everything they have until the last game."

Romelu Lukaku hoped to have answered some of his critics with a hat-trick in Belgium's Euro 2024 qualifying opener at Sweden.

Lukaku scored all three goals as Belgium claimed a 3-0 win in what had looked like being the toughest game of their campaign.

Goals have not flowed so easily at club level this season, with Lukaku returning to Inter and scoring just three time in Serie A – albeit while hampered by injury.

But Friday's game was a step in the right direction as Belgium's record goalscorer said: "It was not an easy game, but we can be satisfied. We did well.

"I am happy that I can play minutes and show the outside world what I can do."

The "outside world" had been an issue for Belgium at the 2022 World Cup, Lukaku suggested, as he reflected following the Sweden game on their group-stage exit.

"I was extremely disappointed," he said, as reported by HLN. "For the first time, we let ourselves be affected by the sounds of the outside world.

"The team has always been close and you saw that today. When I scored, everyone jumped up. We must continue this momentum."

Lukaku's match-winning turn came in the first game under new coach Domenico Tedesco, with Belgium leaving their Qatar disappointment behind in a new era following Roberto Martinez's departure.

"We started to play much more offensively," Lukaku said of their approach under Tedesco. "We haven't had much time to prepare, but I'm happy.

"Change is not a bad thing, as long as the results follow."

Pedri plans to stay at Barcelona for "many years to come" but is not ruling out a move to the Premier League.

The 20-year-old has been a revelation since breaking into Barca's first team, establishing himself as a key player for the LaLiga leaders.

Pedri won FIFA's Golden Boy award for being the best young player in Europe in 2021 and quickly forced his way into the Spain team.

The young maestro is contracted to the Blaugrana until 2026 and has no intention of moving on for now, but suggested he may ply his trade overseas further down the line.

When asked about the possibility of a switch to England, he is quoted as saying by Marca: "At the moment, no. I'm at Barca and hopefully I'll stay here for many more years.

"I love LaLiga, but nothing should ever be ruled out."

Pedri will miss Spain's Euro 2024 qualifiers against Norway and Scotland due to a hamstring injury, but is relishing a new era for the national team under Luis de la Fuente.

Having played under De la Fuente at Under-21 level and in the Tokyo Olympics, Pedri believes the new Spain head coach will be a success.

Pedri said: "He is a person who goes straight ahead, he likes to work on the things he believes in and I think we will do well.

"All the coaches who come try to have the ball and play, especially because of the style of footballers we have, and I think not It will change a lot."

Khadija 'Bunny' Shaw has already prompted comparisons to Erling Haaland for her goalscoring exploits, and a Manchester City team-mate believes she can be the world's best player.

Jamaica striker Shaw has scored 26 goals in 23 games in all competitions for City this season, including 15 in 15 in the Women's Super League.

The 26-year-old has averaged a goal every 86 minutes in the league – not quite on par with men's star Haaland, who has scored every 76 minutes in the Premier League, but close enough for onlookers to note the similarities.

City manager Gareth Taylor did not shy away from comparisons between the "pretty remarkable" pair last week, explaining how both are "so mentally strong".

It is that quality that might yet make Shaw the world's best, with England defender Alex Greenwood backing her City colleague.

"I'm not surprised she's doing what she is doing, and she still has so many levels to go to, which is quite frightening to be honest," Greenwood told BBC Sport.

"I think she can be the best in the world if she wants to be. She has all the attributes to be the best in the world.

"I know how hard she works in training. It's the reason she's flourishing right now.

"She's been really strong for us, so we just need to keep feeding her, keep giving her the ball, and the rest she'll take care of."

Dennis Schroder said the Los Angeles Lakers were grateful to Lonnie Walker IV for inspiring the win that finally took them to .500 for the season and vowed "we're still not finished".

Walker contributed 20 points off the bench in Friday's 116-111 triumph over the Oklahoma City Thunder.

The Lakers, who started the season 2-10, consequently reached the .500 mark after 74 games, representing the first time in over 400 days (January 25, 2022) they have been at that mark.

According to ESPN, it marks the latest a team has reached .500 for the first time in a season since the 2003-04 Miami Heat, who did so after 78 games. 

After the win, Schroder hailed Walker's impact, saying: "He's the guy who won us the game, it's that simple.

"Everybody thanked him for that tonight. This is his win."

Of reaching .500, he added: "Big accomplishment, but we're still not finished."

Those sentiments were echoed by Anthony Davis, who said now is the time to really push on.

"We got to .500, now it's time to get on the other side and have more wins than losses," said Davis, who had 37 points and 15 rebounds.

"So it starts Sunday. We got an opportunity to be a game above .500 against a good Bulls team."

Lakers coach Darvin Ham said: "Now it's time. Instead of constantly facing a deficit, we get to try to create a surplus, create a cushion between the wins and losses. 

"So, the guys are excited about that."

San Diego State coach Brian Dutcher hailed his "fearless" team as they defeated Alabama to book his first trip to the Elite Eight at the NCAA Tournament.

Dutcher is one of six coaches set for an Elite Eight debut this year, the most in a single season since the field expanded to 64 teams in 1985.

None of the other five reached this stage in as spectacular fashion as Dutcher, however, as SDSU upset the number one overall seed 71-64 on Friday.

And Dutcher had a sporting great on his mind as he inspired his players in their unlikely win.

"I just tell the guys: nothing is going to be easy, so just keep playing our brand of basketball, keep doing your best, stay competitive," the coach said.

"And I'm using Muhammad Ali quotes because we're Louisville.

"We talked about confidence, and the key to confidence is being fearless, and I thought we were fearless tonight."

Dutcher does not want this to be the end of SDSU's run, though, adding: "When we recruit, we say our goal is to win a national championship, so we can't act surprised when we have an opportunity to advance to the Final Four.

"It's not just words we use to get them to come here. It's words we believe in."

Despite the disappointment of defeat, Alabama coach Nate Oats attempted to focus on the positives of the past year.

"I'll say it's one of the most memorable seasons ever," he said. "It's not easy to win the regular season, the SEC tournament in the same year and make a Sweet 16 run.

"It's a great group that really loves each other.They're going to be close for life, most of them.

"I love the group, they love each other, and it's just really disappointing that it's ending early.

"But I think it's one of the most memorable seasons in Alabama history, and they can walk out of here with their heads up."

Dallas Mavericks coach Jason Kidd slammed his side's performance as "awful" and "dogs***" and says they deserved to be booed during their 117-109 loss to the Charlotte Hornets on Friday.

Despite having star duo Kyrie Irving and Luka Doncic available, the Mavericks were brushed aside by the under-manned Hornets who are already out of playoff contention.

The defeat significantly hurts the Mavs' own playoff aspirations, slipping outside the play-in tournament spots to 11th in the Western Conference with a 36-38 record after three straight losses.

The home crowd at American Airlines Center made their feelings known, booing the team during a third-quarter timeout when they trailed by 18 points.

"We probably should have been booed in the first quarter," Kidd told reporters. "The effort in the play. They have a right, they paid to see a better show, it wasn’t there until the second half.

"It was awful, dogs***. Understanding the talk before the game with what we're playing for, playoffs or championship, to come out in that first quarter and give up 37, the interest level wasn't high. It was just disappointing."

The Mavs are 7-12 since Irving was traded in from the Brooklyn Nets in February to make them a championship contender. Dallas are 3-7 when Irving and Luka Doncic have played together.

Doncic scored a game-high 34 points with 10 rebounds and eight assists, while Irving added 18 points, nine rebounds and seven assists, but the Mavs were undone after their poor first-half showing.

Irving downplayed the significance of the fans booing the side, despite losing six of their past eight games.

"So what? Just the way I feel about it," Irving said. "I've been in New York City, so I know what that's like. You obviously want to play well, but it's only five people on the court that can play for the Dallas Mavericks.

"If the fans want to change places, then hey, be my guest. Got years of work ahead to be great enough to be on this level. But our focus isn't necessarily on the boos.

"It should be on our performance and just being there for each other."

The Golden State Warriors stormed home to rally back from an 11-point fourth-quarter deficit to down the Philadelphia 76ers 120-112 despite Joel Embiid's 46 points on Friday.

Jordan Poole was clutch with 33 points off the bench including six three-pointers, while Stephen Curry added 29 points on 10-of-18 shooting from the field with eight rebounds at the Chase Center.

Poole made a pivotal three-pointer for a 115-110 lead with 1:18 remaining in the last as the Warriors improved to 39-36 to sit sixth in the Western Conference.

The 76ers had led by 11 points with 11:32 remaining in the fourth quarter after Shake Milton laid off for Paul Reed's alley oop layup, but the Warriors launched their comeback with Poole and Curry at the heart of it.

Poole scored 19 of his 33 points in the fourth period, while Curry stepped up with eight points in the final four minutes.

Klay Thompson added six triples in his 21 points, while Draymond Green had 10 points, seven rebounds and 10 assists in a busy display.

MVP candidate Embiid was huge with 46 points on 13-of-23 shooting from the field with nine rebounds and eight assists.

Tobias Harris added 23 points for the 76ers, with Tyrese Maxey contributing 21. James Harden was absent with Achilles soreness.

Embiid scored 13 straight points for the 76ers in the fourth quarter after checking back in with 8:26 left.

Mavericks slip out of play-in spots

The Dallas Mavericks suffered their third straight loss as their playoff hopes took another hit with a disappointing 117-109 loss to the short-handed Charlotte Hornets.

Luka Doncic scored a game-high 34 points with 10 rebounds and eight assists, while Kyrie Irving added 18 points, nine rebounds and seven assists, but the Mavs were undone after a slow first half, with Hornets forward P.J. Washington managing a team-high 28 points.

The loss leaves the Mavs outside the play-in tournament spots in 11th in the Western Conference with a 36-38 record.

Lakers up to .500 for first time this season

The Los Angeles Lakers squared their ledger at .500 and moved up to eighth in the West with a 116-111 triumph over the Oklahoma City Thunder securing three consecutive wins.

Anthony Davis had 37 points and 14 rebounds for the Lakers, while Lonnie Walker impressed in his return with 20 points and Denis Schroder added 13 of his 21 points in the second half.

The Lakers improved to 37-37 with the win, getting to .500 for the first time this season, with LeBron James' return form injury reportedly not far away. LA are 8-5 during James' latest absence.

Top overall seed Alabama were ousted from the NCAA tournament Sweet 16 after an upset 71-64 loss to San Diego State on Friday.

The Crimson Tide were well below their best in a sloppy performance with 14 turnovers, shooting three-of-27 from beyond the arc.

SDSU's Darrion Trammell scored 21 points as San Diego progressed to the Elite Eight for the first time.

Trammell led the way offensively for the Aztecs, while Nathan Mensah had eight rebounds and five blocks, while Lamont Butler had three steals, four rebounds and four assists.

For Alabama, top-five NBA Draft prospect  Brandon Miller scored nine points with 11 rebounds but committed six turnovers and shot three-of-19 from the field, including one-of-10 from three-point range.

Crimson Tide guard Mark Sears scored 16 points with 10 rebounds but shot none-of-five from beyond the arc.

"Everybody is really disappointed in the loss," Alabama coach Nate Oats said. "It ended too soon."

Midwest regional top seed Houston were also eliminated in the Sweet 16 on Friday after losing 89-75 to Miami.

Hurricanes guard Nijel Pack led the way with 26 points including seven-of-10 three-pointers as Miami made 11 of their first 22 attempts from beyond the arc.

South regional six seed Creighton defeated Princeton 86-75 to set up a Elite Eight meeting with SDSU, after Ryan Kalkbrenner and Baylor Scheierman scored 22 and 21 points respectively.

World number one Carlos Alcaraz wasted no time in advancing to the Miami Open third round with a straight-sets win over Facundo Bagnis in just 64 minutes, while 13th seed Alexander Zverev suffered an early exit on Friday.

Reigning US Open champion Alcaraz eased past Bagnis 6-0 6-2, firing 12 winners and three aces for the match, committing only 11 unforced errors.

The Spaniard won the first set in 24 minutes, marking the first time he has won an opening frame 6-0 at an ATP Masters 100 event. It was also the first bagel he has dished out since beating Bagnis in Umag last year.

"I knew that I needed to be focused for my first match," Alcaraz said after his win, having triumphed in Indian Wells last week. "To start a new tournament is never easy, different conditions.

"I have to be ready to get used to these new conditions, but I was really focused on the match from the beginning, and I'm happy with the way that I played. I try to improve every day."

Alcaraz will face Dusan Lajovic after he beat 30th seed Maxime Cressy 6-4 7-6 (7-2), having knocked off Andy Murray in the first round.

Zverev was the highest seed to bow out on Friday, going down 6-0 6-4 to Japan's Taro Daniel, who beat world number four Casper Ruud last month in Acapulco.

Daniel triumphed in 73 minutes against the German, hitting 17 winners and committing only two unforced errors for the match, while Zverev gave up 18.

The Japanese wild card will meet Emil Ruusuvuori in the third round after the Finn beat 22nd seed Roberto Bautista Agut 6-4 7-6 (7-5) to open up that section of the draw.

Fifth seed Caroline Garcia also crashed out, losing 6-2 6-3 to 74th-ranked Sorana Cirstea, having also recently beaten the Frenchwoman at Indian Wells.

Bianca Andreescu came from a set down to beat seventh seed Maria Sakkari 5-7 6-3 6-4 in a match that lasted over three hours.

Andreescu displayed some of the form that saw her lift the 2019 US Open title, fighting back from a set down and proving composed in the big moments.

The Canadian, who is ranked 31st, will take on 2020 Australian Open champion Sofia Kenin in the third round.
