Pep Guardiola is struggling to convince Bayern Munich's star players of his methods - and could leave the club in the summer, opening the door for some of the Premier League's biggest clubs to make a move.
The Spaniard took over at the Bundesliga club at the start of the season, and helped wrap up the league title in record time.
However since then Bayern's season has started to unravel, and following a string of poor results in the league they were knocked out of the Champions League by Real Madrid in the semi-finals.
According to the Daily Mail, some of Bayern's biggest stars are starting to question Guardiola's methods and in particular his possession-based approach.
"We cannot play to the ideas of the players. This is not possible. We have to play to the idea of the coach.
"After losing vs Real Madrid, I'm even more convinced about my ideas."
Club legend Franz Beckenbauer openly criticised the defeat against Madrid, insisting something was wrong at the core of the club.
"Bayern are not right," he said. "This is something that we have known for weeks. The disappointment is huge."
Reports of Guardiola's precarious position in Germany is likely to put Premier League clubs such as Chelsea, Manchester City and Manchester United on alert.
Chelsea look certain to end the season without a trophy following Jose Mourinho's return to Stamford Bridge.
The Special One's negative tactics are unlikely to have endeared him to Chelsea owner Roman Abramovich, who is reportedly keen on his side playing attractive football which Guardiola would bring to west London.
Manchester United are looking to appoint a manager now and appear to have settled for Dutch boss Louis van Gaal. However, the former Barcelona boss is likely to only be a relatively short-term appointment and could only be handed a two-year deal at Old Trafford.
Manchester City have two former members of Barcelona's board working for them now, and along with Chelsea and Manchester United, were heavily linked with Guardiola while he took a break from the game, before he opted to take charge of Bayern Munich.
