Former Chelsea defender Frank Leboeuf has warned that Manchester United risk relegation from the Premier League if they retain Michael Carrick as manager amid their continuing poor form.

Leboeuf, speaking on ESPN FC, said he could no longer see a solution to the club's struggles and suggested that replacing Carrick might become unavoidable.

Manchester United currently occupy 18th position in the Premier League, inside the relegation zone, following their 4-4 draw against Aston Villa at Old Trafford on Sunday.

The result extended the club's winless league run to eight matches, intensifying pressure on Carrick as the team struggles to move away from the bottom three.

"Nothing is getting good; we don't see any improvement," Leboeuf said.

The former France international, however, acknowledged his support for Carrick but argued that the situation might eventually leave the club with no alternative to changing its manager.

"Again, I am all for Michael Carrick. But there is a time when there will be no other choice but getting rid of him," he said.

Leboeuf added that he could not identify any positive signs suggesting that the team's fortunes would improve if the current situation continued.

"I don't see any solution, I don't see anything getting good, and if they carry on like that you could see Manchester United getting relegated, which is amazing," he warned.

Manchester United's position has raised concerns among supporters, particularly after Nottingham Forest's victory over Manchester City pushed them into the relegation zone before Sunday's fixture.

Despite recovering from a two-goal deficit twice to draw against Aston Villa, Carrick's side remain under pressure to improve their results
