Bayern Munich could pay a high price for their substitution blunder at Freiburg after briefly playing with 12 men in Saturday's Bundesliga game.

The leaders were 3-1 ahead and on the way to a 4-1 away victory when head coach Julian Nagelsmann elected to make a late double change, removing Corentin Tolisso and Kingsley Coman and sending on Marcel Sabitzer and Niklas Sule.

However, Coman did not realise he was being replaced after his number was not raised, and he did not leave the field immediately, with referee Christian Dingert resuming the game before this was noticed.

The game continued for several seconds before being halted as all concerned attempted to make sense of the situation, and the incident may even see Bayern forfeit the win.

German football association (DFB) rules appear to suggest Freiburg could be declared 2-0 winners.

According to paragraph 17, article 4 of the rulebook: "If a player was not eligible to play or be fielded in a game, the team that culpably fielded this player lost the game 2-0 and the opponent won 2-0."

This rule is only to be deployed if the match is allowed to proceed by the referee, as it was on this occasion. A 12th player on the field would be considered ineligible to take part.

Nagelsmann said of the bizarre incident: "The wrong number was on the board, not Kingsley's 11. Mistakes happen. From the point of view of both teams, from the point of view of a fair sport, there was nothing that speaks against it being fair. You play a good game here and then everyone stands there and asks about the rules."

Freiburg coach Christian Streich, appearing alongside Nagelsmann at a post-match news conference, said rules should not be ignored.

Streich said: "I'm sure there won't be an objection, an appeal, from us, but there are rules to be followed.

"There is a rule and there's plenty of speculation, but we have a rulebook and that's what we have to abide by. Everything else, I'm not going to say anything about it, because there's nothing for me to say."

Referee Dingert, quoted by TZ, said: "It was a totally confused situation: It was a double change from Bayern Munich. An incorrect number was initially displayed, which is why the player Coman did not feel addressed with the number 11.

"That's why a 12th player was on the field for a short time, which shouldn't be. We noticed and then stopped the game.

"It's annoying for us because of course that scene is the focus now. We will note this in the game report. The game had 12 [Bayern] players for 15, 16 seconds. No goal happened. We will note that, everything else will be decided by the DFB."

Leon Goretzka, on his return from injury, scored Bayern's opening goal, with Serge Gnabry, Coman and Sabitzer also on target. Nils Petersen's reply was his 100th goal for Freiburg in all competitions.

Victory kept Bayern sitting pretty at the top of the Bundesliga, taking them nine points ahead of Borussia Dortmund who were not in action until later on Saturday against RB Leipzig.

Thomas Tuchel said Chelsea "stopped defending" as Brentford ran riot in a sensational 4-1 derby victory at Stamford Bridge.

Brentford stunned the European champions on Saturday, emphatically securing a first win over their west London rivals since 1939.

Antonio Rudiger's long-range thunderbolt put the Blues in front early in the second half, but Thomas Frank's side hit back with three goals in the space of 10 minutes.

Vitaly Janelt struck twice either side of Christian Eriksen's first goal for Brentford and Yoane Wissa added a fourth in the closing stages just after coming on.

Chelsea had won five consecutive games since Roman Abramovich put the club up for sale, but they were picked off time and again as rampant Brentford moved 11 points clear of the Premier League relegation zone.

Blues head coach Tuchel felt his side's performance was out of character ahead of a Champions League quarter-final first leg against Real Madrid on Wednesday.

He told BBC Sport: "Nobody saw it coming, especially after going 1-0 ahead. It was very untypical of us. But we stopped defending. We were not aware of enough of the danger, were sloppy with the defending and got punished.

"They made the most of it in those 10 minutes. Right after their third goal we had 10 minutes where we had big, big chances and we missed them.

"They were lucky and clinical enough to get three goals. We did not defend like it is needed to in the Premier League and got punished."

Tuchel had expected third-placed Chelsea to be vulnerable in their first game back after the international break.

He explained: "The start was not a surprise because we came from all over the world from national duty so I expected it to take time. The first 25 minutes we looked a bit leggy and needed to find rhythm.

"The opponent defended deep with 10 men behind the ball, so you need a shot or action to open the game, which we did. Then we gave the game away very cheaply."

Chelsea will now regroup before doing battle with LaLiga leaders Madrid at Stamford Bridge in midweek.

"It is not about Real Madrid. It is about us. It is one day off now and on Monday we start again," he said.

Mahmudul Hasan Joy scored Bangladesh's first Test century against South Africa to lead the tourists back into contention in the first Test.

Bad light brought a slightly premature conclusion to proceedings on day three, with South Africa 75 runs ahead having bowled Bangladesh out for 298 and started their second innings 6-0.

But this was a day for the Tigers and opener Mahmudul (137) to reflect fondly on in Durban.

Mahmudul had been their one shining light on day two in only his third Test, unbeaten on 44 at stumps with his team a concerning 98-4 in reply to the Proteas' 367.

Nightwatchman Taskin Ahmed departed in only the third over of Saturday's play, but Mahmudul finally found a team-mate able to stick around in Liton Das and the pair put on 82 for the sixth wicket.

Mahmudul was dropped by Sarel Erwee on 64 and reached 90 before he inadvertently had partner Yasir Ali – the next man in after Liton – ran out.

A landmark century kept Bangladesh moving, though, and their innings only ended when Mahmudul's did, with the 31-year-old not quite able to carry his bat after playing with greater ambition alongside the tail, caught by Simon Harmer at slip.

Marvellous Mahmudul makes history

The previous high score from a Bangladesh batsman against South Africa had been Mominul Haque's 77 in 2017, a mark Mahmudul cleared by some distance.

He survived 326 balls and almost seven and a half hours, scoring 15 fours and a pair of sixes. Six of those boundaries came across two overs after Mehidy Hasan Miraz departed late in the innings.

No first five-fer for Harmer

South Africa remain in control of the Test match, but they allowed Bangladesh to retain some hope by failing to follow up their superb early bowling from the previous day.

Harmer finished Friday with outstanding bowling figures of 4-42 from 20 overs, yet he allowed 61 runs for no wickets from his next 20, improbably unable to claim a first five-fer. At least he had his day two efforts to fall back on; Keshav Maharaj finished on 0-65.

Jurgen Klopp knows his team must continue winning to keep the Premier League title race alive after recording a 10th consecutive league victory against Watford.

The Reds briefly went top of the Premier League after the 2-0 victory at Anfield thanks to a first-half header from Diogo Jota and a late penalty from Fabinho.

Klopp acknowledged that any question about moving ahead of Manchester City by two points would be null and void after discovering Pep Guardiola's men had already taken the lead at Burnley before he had even started his post-game media conference. The reigning champions, who host Liverpool nextwent on to win 2-0 at Turf Moor.

Klopp told reporters: "No, you can't give an inch, but it's nothing to do with being on top of the table, I didn't think about that in the moment, I was just happy to win the game and having now 72 points.

"To keep it a title race we have to win our football games, otherwise it will be really tricky. And the next Premier League game obviously is a big one [against City], we do not hide from that. It's all good. But now we have a Champions League game to play, which is as important, and three days' time to prepare that. Then we go from there."

Liverpool were not at their best against the Hornets but secured the three points and another clean sheet, meaning they have now kept five consecutive clean sheets in the Premier League for a second time under Klopp, previously doing so in January 2020 (a run of seven).

Part of the backline today was Joe Gomez, making just his second league start of the season, and Klopp was pleased with the 24-year-old's efforts filling in at right back.

"He did really well and he could have set up a second goal in the second half, the cross was an incredible one as well.

"Defensively we don't have to talk, offensively some really good moments and some not-so-good moments because you see the positioning against a deep-sitting opponent, it is not so easy to find the right position in these moments and we are usually a bit more flexible, but it’s all fine.

"Joe is an outstanding football player and he will play a lot of games during his career, 100 per cent, he will play here a lot of games definitely. This season was tricky so far for him, but who knows how these things can change. He is obviously ready to use the opportunity when he gets it."

Gomez's accurate ball in the 22nd minute found the head of Jota, who grabbed his 20th goal of the campaign.

The Portugal international also had words of praise for Gomez, telling Liverpool's official website: "I spoke with Joey before the game, I said: 'You are going to get an assist today!' I remember against Nottingham [Forest] he had a few crosses that I couldn't get on the end of, but I was confident for today and fortunately for us it happened.

"It's the first time in my career that I reach 20 [goals], so just keep on going because we still have plenty to play for."

No player has scored the opening goal in more Premier League games this season than Jota, with Liverpool going on to win all six games in which he has opened the scoring for them.

Cristiano Ronaldo was not part of Manchester United's squad for Saturday's Premier League home game with Leicester City due to illness.

The 37-year-old played both World Cup qualifying play-off games for Portugal during the international break, but he was struck down by flu on Friday and was not ready to face City.

Ronaldo has scored 18 goals in all competitions since returning to United in August, with 12 of those in the Premier League, including a hat-trick against Tottenham in his most recent outing in the competition.

Confirming the reason behind Ronaldo's absence, Rangnick told MUTV pre-match: "He had some flu-like symptoms before training yesterday and didn't feel well enough to train.

"We sent our doctor to his home this morning to check if he felt any better, but he didn't, so he's not in the starting XI as he was supposed to be."

Prior to the visit of Leicester, United had failed to win any of the five top-flight matches they had started without Ronaldo since the five-time Ballon d'Or winner rejoined.

Despite the absence of Ronaldo, and with Edinson Cavani again being ruled out through injury, Marcus Rashford had to settle for a place among the substitutes.

Rangnick instead went with the same system and side that started last month's 4-1 loss to Manchester City when Ronaldo was last absent.

Captain Harry Maguire, jeered by a section of England supporters during a friendly in midweek, retained his place in defence.

As for Leicester, who had won their past three games against United in all competitions, they paired Wesley Fofana and former Red Devils man Jonny Evans together in defence for the first time this season.

Vitaly Janelt scored a classy double and Christian Eriksen opened his Brentford account in a sensational 4-1 derby win over Chelsea at Stamford Bridge.

The Bees were the better side in the first half, but it was the Blues who took the lead just after the break through an Antonio Rudiger thunderbolt from long range.

Magnificent Brentford responded to that blow by scoring three times in the space of 10 minutes, Janelt on target with two brilliant strikes either side of Eriksen's clinical finish at the end of a devastating counter-attack.

Yoane Wissa added a late fourth goal as the Bees ran riot in a first victory over Chelsea since 1939, ending their London rivals' six-match winning run to move 11 points clear of the Premier League relegation zone.

Edouard Mendy was fortunate to get away with a terrible pass just five minutes in, with Ivan Toney letting the stranded Blues goalkeeper off the hook when his lob floated over the crossbar.

Toney had a shot palmed wide by Mendy and the wasteful striker headed off target from close range in an impressive start from Brentford.

Chelsea looked short of ideas, but Hakim Ziyech finally called David Raya into action with a rasping left-foot drive after he was picked out by Mason Mount in the penalty area.

Rudiger produced a moment of quality that the Blues had been so badly lacking to open the scoring three minutes into the second half, letting fly with venomous right-foot strike from 35 yards that flashed past Raya.

Chelsea's joy was short-lived, though, as Janelt rounded off a well-worked move by drilling Brentford level with his left foot two minutes later.

The Bees ripped the Blues apart with a brilliant counter-attack to take the lead four minutes after that equaliser, Eriksen applying the finish with his left foot after Bryan Mbeumo spotted his surging run into the box.

Thomas Frank's side continued to knock the ball around with a swagger and they were rewarded with a brilliant third goal on the hour-mark, Toney threading a perfectly weighted pass into the path of Janelt, who coolly dinked the ball over Mendy and into the back of the net with his left foot.

Wissa added insult to injury just after coming on, rifling home with his right foot after a mix-up between Rudiger and Thiago Silva with Chelsea all at sea.

Manchester City will go into next week's huge clash with Liverpool with a one-point lead at the Premier League summit after beating Burnley 2-0 to reclaim top spot.

Liverpool defeated Watford by the same scoreline in Saturday's early game to leapfrog the reigning champions, but the Reds' stay in first place was a short one.

Kevin De Bruyne and Ilkay Gundogan netted inside the opening 25 minutes and City sauntered to a 10th consecutive victory over Burnley.

Gabriel Jesus missed chances to add to City's lead, but there was never any danger of a Burnley comeback as City ensured a narrow advantage ahead of Liverpool's trip to the Etihad Stadium on April 10.

Where Jurgen Klopp's men laboured a little in their win against relegation-threatened opponents, City were in control almost from the outset – although Burnley had the first chance, when Josh Brownhill's third-minute header beat Ederson but dropped wide.

City led just over two minutes later, as Raheem Sterling cushioned Rodri's cross into the path of De Bruyne, who thumped high past Nick Pope.

The same two players combined again for City's second, playing a one-two on the right that set Sterling away to tee up a Gundogan shot, which earned a slight deflection off Kevin Long on its way past Pope.

Burnley enjoyed an improved spell following a succession of Pope saves at the start of the second half, but they failed to trouble Ederson in the same way and could have been in three behind when City substitute Jesus volleyed an awkward effort just over.

Jesus would go away wondering how he had not got on the scoresheet after Connor Roberts deflected another volley against the foot of the post, before the forward shot wide on the rebound.

Leon Goretzka returned from his long lay-off with a goal as Bayern Munich won 4-1 at Freiburg in the Bundesliga – where the leaders briefly had 12 players on the pitch.

Freiburg are in the hunt for a Champions League place and were far from pushovers, despite having won just one of 37 previous Bundesliga clashes between the teams.

Their resistance was broken when Goretzka, back from a hip injury that had kept him sidelined since December, headed a 58th-minute opener.

Freiburg's Nils Petersen scored within moments of coming off the bench to bring Freiburg level, only for Serge Gnabry to do just the same for Bayern in the 73rd minute, and Kingsley Coman drilled in the third before Marcel Sabitzer hit a fourth in stoppage time.

Thomas Muller, Joshua Kimmich, Leroy Sane and Goretzka threatened early on from Bayern half-chances, before Manuel Neuer comfortably saved a daisy-cutter from Roland Sallai at the other end.

It was just the sixth time this season that Bayern had failed to score in the first half of a Bundesliga game, but they had not drawn a blank over 90 minutes.

Therefore, it was hardly a surprise when Goretzka made a 58th-minute breakthrough, heading in Kimmich's free-kick after Mark Flekken made a misjudged charge off his line and failed to claim the ball.

Goretzka came off after 62 minutes, receiving a hug from Julian Nagelsmann, who also removed Robert Lewandowski. But within seconds it was a Freiburg substitute, fresh from replacing Sallai, who stunned Bayern with a fine equaliser.

Petersen made a bright run between Bayern defenders to meet Christian Gunter's clever pass and drill a left-footed strike across Neuer, finding the bottom-left corner.

Gnabry pulled off the same trick of scoring within seconds of entering the action when he restored Bayern's lead, taking advantage of charitable defending from Nico Schlotterbeck to fire left-footed into the bottom-right corner after Lucas Hernandez's cross. Coman struck when Flekken could only push his skidding 20-yard strike into the net.

Play was held up for several minutes when Bayern briefly had 12 players on the field, after an apparent substitution bungle, but the game continued when that was resolved and Sabitzer struck late on to add gloss.

Daniil Medvedev has confirmed he will undergo a procedure to fix a troubling hernia issue, which may keep him out of the French Open.

Medvedev, who enjoyed a short-lived stint as world number one at the start of March before relinquishing the crown back to Novak Djokovic, reached the quarter-finals at Roland Garros last year.

However, the chances of the Russian appearing in Paris now seem slim, given he faces up to two months out of action following the impending operation.

This year's French Open runs from May 22 until June 5.

"Hi everyone," the world number two tweeted on Saturday. "The last months I have been playing with a small hernia.

"Together with my team I have decided to have a small procedure done to fix the problem. I will likely be out for the next 1-2 months and will work hard to be back on court soon. Thanks for all the support."

Medvedev had been hoping to use the clay court swing to reclaim top spot in the ATP rankings.

He could have done so had he reached the semi-finals of the Miami Open last week, yet the 26-year-old lost 7-6 (9-7) 6-3 in the quarters to Hubert Hurkacz.

Medvedev appeared to be struggling in that tie and after the defeat he told reporters: "All the match I was not feeling my best. But, you know, sometimes it happens.

"I don't know the actual reason. Maybe the heat. But I was feeling super, like, dizzy, tired, and there was this long game where I couldn't serve anymore.

"Then in the locker room I was cramping quite much, so physically was not easy. But at the same time, that's part of the game."

Should Medvedev fail to return in time to make the season's second grand slam, the reigning US Open champion will hope to be fully firing by the time Wimbledon comes around in late June.

Paulo Dybala is coming to the end of his Juventus career, but Massimiliano Allegri will throw the Argentina forward into Sunday's Derby d'Italia regardless.

It could be Inter that Dybala plays for next season, as they reportedly court the 28-year-old who is entering the final months of his Juventus contract.

But this weekend the Nerazzurri will be the opposition as Dybala looks to help Juventus continue their surge up the table.

Victory at the Allianz Stadium would lift Juventus above faltering Inter and into third place, with the Scudetto perhaps not entirely off the table, despite Allegri's protestations they are not part of the title battle.

Amid intrigue over whether Dybala could miss out, Allegri backed him to make an impact in the biggest match of the weekend's Serie A schedule.

"Dybala will start the game," Allegri told a news conference on Saturday.

Talks over a new contract for Dybala broke down in March, meaning he can leave on a free transfer, and Allegri said Juventus agreed that outcome would be for the best.

"We are in agreement with the club on everything," Allegri said. "There is always a unity of purpose to move forward. The choices are made together.

"When we talk, I present my ideas and the company its own, and then in the end we always find unity of purpose to plan. We plan everything together.

"I don't think it's the first case of a player changing clubs. Right now, we need to be focused for the season finale."

Dybala has scored a modest three goals in his 10 previous Serie A games against Inter.

Allegri smarted at the mention of speculation over a possible move for Dybala to Inter, and for Paul Pogba to Juventus. Like Dybala, Manchester United's Pogba, a former Juve star, will be a free agent come the end of June.

"Dybala at Inter and Pogba at Juve? I don't do my own transfer market, let alone those of others," Allegri said, quoted by Gazzetta Dello Sport.

Inter looked strong favourites for the Serie A title earlier in the year but have taken only 11 points from their last nine Serie A games (W2 D5 L2), while Juventus have taken 21 points in the same stretch to hurtle into a strong fourth spot, closing in on the top three.

A 1-1 draw at San Siro when these teams met in the league in October was followed in January by Inter edging Juve 2-1 in the Supercoppa Italiana.

"It's not easy to say who is favourite in the Derby d'Italia," Allegri said. "We have been following our path steadily, and we are ready to face Inter... maybe it's our turn to win this fixture.

"Inter, together with Milan and Napoli, are one of three candidates for the Scudetto. As for Juventus, we need to keep our focus on fourth place. That's the position we are in right now but Atalanta are breathing down our necks. Our aim is to qualify for the Champions League next season."

Allegri's Juventus have recently pulled clear of Atalanta, who headed into the weekend nine points adrift of the Turin giants, albeit with one game in hand. This has come about due to Juventus having the longest current unbeaten run in Serie A – a stretch of 16 games (W11 D5).

Liverpool moved above Manchester City at the top of the Premier League with a 2-0 win over Watford in Saturday's early kick-off at Anfield.

The Reds knew that victory would see them leapfrog City, who face Burnley later in the day, for the first time since November 27 – even if only for a matter of hours.

Diogo Jota headed in from a Joe Gomez cross after 22 minutes to open the scoring and substitute Fabinho sealed a battling win with a penalty in the final minute.

Liverpool have now won 10 league games in a row ahead of next weekend's huge showdown with City, who are two points worse off with their game at Turf Moor to come.

Watford more than held their own in the early stages of the game and would have been in front if not for a good stop from Alisson to deny Juraj Kucka.

That proved a huge save as, a little over 30 seconds later, right-back Gomez – filling in for Trent Alexander-Arnold – whipped in a cross for Jota to turn in from four yards. 

Jota nearly made it 15 league goals for the season shortly after, only to be denied by Ben Foster when he had Jordan Henderson screaming out for the pass alongside him.

Watford, in action for the first time in three weeks, continued to cause Liverpool problems as Joao Pedro fired wide in plenty of space once played in by Ismaila Sarr.

Jota saw a couple of headed chances come and go but Fabinho made certain of the win when thumping in a late penalty, awarded for Kucka dragging down Jota in the box.

What does it mean? Reds set up tantalising showdown

Liverpool were never at their best but got the job done to become the second club, after City, to record five different runs of 10 or more victories in the Premier League era.

The Reds have kept eight clean sheets during that incredible run and will head to the Etihad Stadium next weekend with wind in their sails.

They have now won 13 of their 14 home league games against Watford, who remain in the relegation zone and are running out of fixtures to drag themselves out of danger.

Gomez fills Trent void

No player has scored more opening goals in the Premier League this season than Jota (six), who had a brilliant Gomez cross from the right to thank for his latest headed goal.

That was Gomez's first assist in the top flight since December 2017 and means Liverpool have had 22 players involved in league goals this term, two more than any other side.

Salah's off day

Salah had previously been directly involved in 11 goals in seven league games against Watford, averaging a goal involvement every 57 minutes, but he was off the pace here.

He suffered World Cup qualifying heartbreak with Egypt in the week and that perhaps told as he failed to find the target from any of his three attempts.

What's next?

Liverpool travel to Benfica for the first leg of their Champions League quarter-final on Tuesday, while Watford host Leeds United on their return to league action in a week's time.
