Man Utd boss Ferguson: Rafael better for Ronaldinho clash
Ferguson acknowledged that Ronaldinho had shown he was "back to his best" and admitted that Rafael had found the former world footballer of the year a "difficult handful".
He added: "The reason I played him was quite simple, namely that we have invested in a great future and we were not going to stop the rewards of that because we were playing AC Milan.
"He has to learn, against Ronaldinho, that this is the real world. He [Rafael] made some mistakes, but he won't make them next season. He will eradicate those mistakes because the boy is an outstanding talent."
