The Red Devils legend says he would welcome the Portuguese coach back to Old Trafford, pointing to his proven record of winning trophies.
Mourinho guided United to Europa League and League Cup success between 2016 and 2018 before departing on difficult terms.
"He’s a winner and can carry that football club, but the powers that be would never allow it, as they now prefer a manager who focuses solely on coaching rather than controlling recruitment," he told Paddy Power.
“No established manager will want to come to Manchester United without guarantees on budget, time, and control. The structure right now makes it difficult, and they may prefer someone like Michael Carrick instead.”
