Ryan Giggs thinks United's form this season is down to the return of Paul Scholes.
"We have seen now how much we missed him last season when he was out,” said Giggs.
"At the time it was such a mystery, so everyone was a bit worried.
"He doesn't say much, so we didn't know fully what was going on and he was still out there at times booting the ball around the training pitch. But it was a concern.
"We are pleased to have him back playing so well, because there is no other player like him. He is class."
Arsenal's Cesc Fabregas is also an admirer
He said: “Paul Scholes has had a fantastic season.
“He is a very complete, spectacular footballer. He always fights for the ball and tries to lose his marker to help his team-mates — either to defend or to have a shot on goal.
“For any football player in the Premiership, Scholes is a player you want to emulate.
“One player does not make a team but there is no doubt that the presence of some players add extra motivation and confidence.
“Scholes is a player with character and is capable of transmitting that mental strength to his team-mates.
“I would happily end my career with the medals that Scholes has. He has six league titles, four FA Cups, one European Cup and one Inter-Continental Cup to his name.
“I am young and I hope that I will be able to surpass him — but it is not going to be easy.”
