Arrigo Sacchi has backed AC Milan's bid for Barcelona star Ronaldinho.
"Ronaldinho can be the right man to revive Milan, but he will need to be able to stay on the field. He is often subject to injuries and this could be a big doubt hanging over his purchase.
"In this regard, I always wonder why Milan is always gambling with their transfers. It's happened already with Emerson, (Fernando) Redondo and Ronaldo."
