Hernan Crespo is supremely confident that Manchester United can return to former glories under Jose Mourinho.

The Argentine striker played under the Portuguese at Chelsea and Inter Milan while also playing alongside a young Zlatan Ibrahimovic in Italy.

Writing in his column for The Guardian, Crespo explained why he believes the pair will have an enormous impact at Old Trafford after a few lean seasons experienced by the Red Devils.

“It was incredible to work with Zlatan Ibrahimovic and Jose Mourinho," he wrote.

“They are two winners with great personalities, two real football people. The Manchester United fans can really look forward to having two world-class people at the team, one on the bench and one on the pitch.

“The two of them can turn Manchester United into winners again.

“That winning mentality is something that has been missing a little during the David Moyes and Louis van Gaal spells in charge and Mourinho, as a manager, is the ideal person to bring it back. He is a manager who always knows how to create something special wherever he has been.

“Ibrahimovic, meanwhile, is a striker who wins games for teams, as simple as that.

“Zlatan and Jose are extraordinary people and this, to me, demonstrated that. I wish them all the best at Manchester United.

“Seeing them together again will be beautiful. I think it will be a successful reunion."
