The alarm bells are ringing at Manchester United after their Champions League humiliation on the shores of Lake Como. The Red Devils are enduring a run of seven games without a win, and Michael Carrick is reportedly fighting to save his job.According to The Telegraph, United's hierarchy is preparing to decide on the manager's future, with Julian Nagelsmann already emerging as a potential replacement.The report claims the club have made contact with the German and that discussions are ongoing. Carrick's position is said to be hanging in the balance until a possible deal is finalised, with Nagelsmann reportedly keen on the prospect of taking charge at Old Trafford.Bruno after disaster: "It's a decision from the staff to not press"Next weekend's clash with Bournemouth could therefore prove decisive for Carrick. The Cherries have not lost to United in three years, while growing public criticism from the players has added to the pressure on the current manager.United's hierarchy have backed Carrick until now, but their patience is reportedly wearing thin. Bruno Fernandes' comments criticising the coaching staff's tactics on Wednesday night were seen as another warning sign, fuelling suggestions that Carrick may have lost the dressing room.With the players seemingly no longer prepared to shield their manager from scrutiny, the Bournemouth match could become a defining moment in his tenure.##EDITORS_CHOICE##Antonio Conte has also been offered to United through intermediaries and agents, but the club are reportedly unconvinced by the Italian's rigid tactical approach and demanding personality.Nagelsmann, by contrast, is viewed as a more modern option who could better suit the profile of United's current squad.The German has been available since the World Cup, following his departure from the national team. Speculation linking him with a return to RB Leipzig has recently quietened, and the report suggests that even an offer from his former club would struggle to match the appeal of Manchester United.He has been linked with the Old Trafford job before, but previous opportunities never resulted in an agreement as he opted for other projects. This time, the circumstances could be different.22.00: (3.00) Jagiellonia (3.30) Anderlecht (2.25) One potential driving force behind his appointment is United director Christopher Vivell, with whom Nagelsmann previously worked at Leipzig. Their existing relationship could help facilitate a move.If Carrick is dismissed, United would be facing their third mid-season managerial change in three years.Erik ten Hag was sacked in October 2024, while Ruben Amorim was dismissed in January this year. Another change would underline the club's continuing struggle to establish stability in the dugout.
