Speaking to Italian website 7ITV.tv, Moggi said: “That's not because he isn't worth the money but because he plays at a moderate pace, even though he knows how to do everything with his feet.
“But things are different in Italy and when the tempo increases Ronaldinho just stays the same. He just watches the game and maybe does something from a free-kick.
“I think Dinho finds it difficult when he plays with Kaka up front. I think the Rossoneri made a mistake in signing him - they should have bought a defender.”
