Legendary former Manchester United boss Sir Alex Ferguson believes Jose Mourinho’s arrival at the club will give it a massive boost. 

Mourinho has taken over the reins at the club three years on from Ferguson’s resignation, following a trophy-laden 26 tears in charge of the club in which the Scotsman won 13 Premier League titles and two Champions Leagues.

‘I think he’ll be a massive improvement, I really do,’ Ferguson told Sky Sports television on Tuesday, reports Evening Standard.

‘I thought Jose was wrong to go back to Chelsea…I think it is always difficult to go back somewhere for a second time,’ Ferguson added.

Mourinho led Chelsea to the title upon his return to London, but then endured the most disastrous season of his career, eventually getting sacked with the club in free fall. Ferguson, however, believes Mourinho’s record speaks for itself.

Ferguson, however, believes Mourinho’s record speaks for itself.

‘But in terms of ability, charisma, personality, success he’s had, he’s won the Champions League with two different clubs [Porto and Inter Milan], he won league titles with all the teams he’s been at…his record, you can’t ignore.

‘I think United is the right kind of club for him and I think he’ll do really well.’

Mourinho is the third manager to take charge of the Red Devils since Ferguson quit the club, with David Moyes and Louis van Gaal each struggling to replicate Ferguson’s success.
