Chelsea boss Carlo Ancelotti believes Juventus will be the big movers this season.
He told Tuttosport: "I am very curious to see how Diego will play for Juventus. He is an excellent trequartista. I'm also interested in Palermo's [Javier] Pastore, as he is young and can become a great midfielder. Some already consider him the heir to Kaka.
"Juventus have closed the gap on Inter with the arrival of Diego and Felipe Melo, while Fabio Cannavaro will also be very useful in a World Cup year. They'll fight to the end for the Scudetto."
