Arsenal captain Gilberto Silva says Anderson can be "fantastic" for Manchester United.

"If Anderson stays where he is, he can be fantastic," Gilberto told the Observer. "He makes the difference because he can score goals and come back to mark. He has a good technique and so much pace in his game. It's not that easy for a Brazilian to adapt to English football in the first season, but he's done it already - and in a new position."
