Italian coaching expert Walter Novellino believes AC Milan have pulled off a coup with Kaka's signing.
The midfielder signed yesterday from Real Madrid - four years after leaving the Diavolo for the Spaniards in a 65m deal.
Novellino declared: "Milan have made an extraordinary deal with Kaka, even if he is in need of repair.
"Usually such returns flop, but he really wants to do well, he will become crucial to the game of (coach Max) Allegri."
