Jamie Carragher has warned Manchester United they would be betraying decades of history if they appoint Jose Mourinho.
The former Liverpool star believes appointing the recently fired Chelsea boss would show that United are scared of their rivals, as well as arguing that stylistically he is a poor fit for the club.
Speaking to SkySports Monday Night Football, Carragher argued that while Mourinho would bring success, it could be detrimental to the club's youth policy.
He said: "I'd say no. Winning trophies, Jose massively ticks that box. Bringing young players through, no, playing exciting football, cut-throat football, going for every game, he doesn't tick that box either.
"So if that is someone that they go for, I think it will show the fear Manchester United board have, maybe some of the supporters chanting for him at the weekend have of other teams getting away from them, and also Pep Guardiola may be going to Manchester City.
"They are actually going to forget some of the principles that have made the club what they are over the past 50 to 60 years, they are that desperate to get back to winning trophies."
Louis van Gaal remains the manager of Manchester United, but his job is under intense scrutiny.
The Red Devils are fifth in the league, and have suffered back to back defeats to Norwich City and Bournemouth, also exiting the Champions League at the group stages, winning only two of six matches.
The United side are playing a dour brand of football, and whether Mourinho is the man to change that remains to be seen, but the chances of him winning more matches with them, could be worth taking a gamble on.
