Freedman said: "He won't be fazed by it, that's for sure. I've known him since he was 12. I wouldn't say he's cocky off the field but on it he has a certain arrogance.
"He expresses his talent in any surroundings and that will be no different at Manchester United.
"I believe that young man will go into that team and surprise a few people. He's hard-working, dedicated and will show United he's a wonderful player.
"Wilfried is a fantastic young man who deserves everything he gets.
"He's worked very, very hard and has dedicated himself to his game."
