Louis van Gaal has hailed new Manchester United signing Angel Di Maria but warned that he does not expect the Argentine to produce miracles immediately.
Di Maria completed his British transfer record 75 millon euro move to Old Trafford on Tuesday and has been handed the iconic No.7 shirt by the club.
The Argentine could make his debut against Burnley on Saturday but Van Gaal has warned fans not to expect too much too soon.
"I am very pleased that we can have a such a class player in our squad," he told reporters. "We have many class players but it is important he is a team player.
"Di Maria can accelerate the game for us and also play in the interests of the team. I hope he will give us good results.

"We cannot expect him to be the miracle after two of three days of training. We have to be the miracle. You have to work for miracles and he knows that."
The Dutch boss has been on the look out for players to fit his specific requirements all summer, and he believes Di Maria's versatility will be key to what he is trying to do at Old Trafford.
"He fits in our philosophy... he played at Real Madrid not only as a wide player but also in the center of midfield," he added. "That is why we are convinced he will succeed.
"He will be a player who enjoys defending and that's also a reason we have chosen him. But when you see him, you see that he is a very modest guy, he wants to work, he showed that also last year, he played 52 matches and he provided 22 assists.
"How many players can say that? Twenty-two assists! He is a very [humble] human being and in the football world that is not always the case, as you know."
