"Was I disappointed by his attitude? Not at all, I found him to be very serious and focused," explained Moratti on Sky Sport Italia.
"He stayed for his father, who he is extremely close to, and for his whole environment. Therefore he was unable to create that split that they expected and we were hoping for."
Moratti added: "Mourinho did hope for this move, but we knew it was going to be difficult.
"So instead we thought of a player who in terms of age and wages is a good deal: I am happy that Sulley Ali Muntari has arrived."
