Steve Bruce insists Jose Mourinho is the man to return Manchester United to the top of English football.
Mourinho has faced heavy criticism this season with United supporters not enamoured by the style of play and rivals Manchester City running away with the Premier League title.
Reports have emerged this week that the self-styled Special One could quit Old Trafford at the end of the season, leaving United to look for their fourth boss in five years.
But Bruce says his old club, who have failed to win the Premier League since Sir Alex Ferguson retired in 2013, should be doing everything to keep hold of the 54-year-old for the long-term.
The legendary former United defender said: “I’m the biggest Jose Mourinho fan there is.
“What he has won, what he has achieved over the last 15 years – nobody will want him to leave Old Trafford I wouldn’t have thought.
“He is the right man for the job. He gets harshly criticised.
“He is an unbelievable manager. How we can criticise him is quite unbelievable really.
“He won two trophies last year and if he stays in charge then Man United will get back to where they ought to be.”
