And Scholes reckons his old club can achieve great things with Mourinho at the helm - backing them to finish third at the end of the season.
"It's been a massive improvement from what we've seen in the last couple of years," he told the
Daily Mail.
"The first two or three months weren't great but they've turned it around.
"There's a way of playing that the fans are enjoying.
"The only problem is they're still sixth, which after being in such good form is a bit of a worry. But I watch them now and have no doubt they'll finish in the top four.
"They're playing the best out of the top six with Chelsea and you have to fancy them to finish second or third. Probably third if I had to nail it down."
Scholes was openly critical of former United bosses David Moyes and Louis van Gaal.
But the former England international has admitted he would be happy to play in Mourinho's team.
"Yes, definitely," he added.
"There is a speed and desire to score goals which win games."
