Michael Carrick has come under further pressure as Manchester United head coach after his side suffered a heavy 4-1 defeat to Champions League debutants Como

Julian Nagelsmann has been approached about replacing Michael Carrick as Manchester United manager amid the club's poor start to the season. United have won just twice across the Premier League and Champions League this campaign, with Wednesday night's 4-1 defeat to Como extending their winless run to seven matches in all competitions.

The European setback has intensified scrutiny of Carrick, while captain Bruno Fernandes questioned the coaching staff's decision not to adopt a man-to-man press. Sunday's home clash with Bournemouth could prove crucial to Carrick's future, and United are reportedly already exploring potential replacements.

According to talkSPORT, Nagelsmann has emerged as a candidate to succeed him. The former Germany manager is available after stepping down from his national team role.

Nagelsmann is said to have admirers within United and featured prominently in the club's thinking before Carrick was appointed on a permanent basis. The German is also reported to be open to taking the job.

The 39-year-old speaks perfect English and has previously worked with United's director of recruitment, Christopher Vivell, at RB Leipzig.

Brighton boss Fabian Hurzeler is also reportedly high on United's shortlist, having impressed during his time on the south coast. However, his recently signed long-term contract could leave United facing a substantial compensation bill if they pursue the German.

Antonio Conte and Eddie Howe are also available, with Conte having left Napoli in the summer. Former Newcastle manager Howe is regarded as a straightforward appointment given his free-agent status.

Howe was previously favoured by former United sporting director Dan Ashworth, although minority owner Sir Jim Ratcliffe reportedly opposed a move.

While talkSPORT add that Carrick did not arrive at Carrington at his usual time of 7.30am on Thursday, he is still expected to oversee Sunday's Premier League clash with the Cherries (2pm kick-off).

The United boss hinted at the scale of his anger over United's performance on Wednesday evening. ’m bitterly disappointed,” he said.

“I’m frustrated, more than frustrated, I’m really angry to be honest. You’ve got to move on and think about what’s next. For us to play in that way is not acceptable, it wasn’t a good performance at all.”
