ROY KEANE AND PETER SCHMEICHEL WERE CLASS PLAYERS AS WELL.
Sir Alex Ferguson says that he only had four world class players.And they were .
1) Paul Scholes.
2) Cristiano Ronaldo .
3) Ryan Giggs.
But we must remember that in those 27 years there were other world class players no doubt about it.
1) Roy Keane .
2) Peter Schmeichel .
These two were really world class, and we must also see how much did they cost Manchester United as well.
