Schmeichel won the Champions League with United in 1999 and has happy to see United play their best performance of the season so far.
Speaking on Sky Sports Schmeichel said: "It is the best I have seen United play this season. It looks like Van Gaal may have listened to us - a little change of personnel, with Rooney playing off Martial, who was playing through the middle.
The Dane was quick to praise Wayne Rooney who scored the winner and was under pressure before the game for some uninspiring performances in recent weeks.
Schmeichel added: "And actually Rooney played really, really well. It looks like that is his position. Late on, he got into the No 9 position and he scored from that, but he drops deep, can pass the ball - he has a little bit of the same ability as Paul Scholes in that he can drop deep and put those long balls into the corners for the quick players to run for. And I thought he played really, really well today."
