Lee Sharpe is backing former Manchester United teammate Ryan Giggs for the top job.
Giggs is currently Louis van Gaal's assistant and the Dutchman has previously named him as his successor when he leaves Old Trafford.
"I'd like to see him have a go but it's another tough one," Sharpe told Soccer AM.
"The man's a legend and to go in there and fail after six months to get the sack, it ruins his credibility a little bit.
"But I do think he's got as good a chance as anybody of being a success at Old Trafford. He knows the club. He knows what it needs.
"I just hope he's get someone in around him who's a bit more experienced to help him out. I think he'd be great."
