Juventus coach Alberto Zaccheroni blames Vincenzo Iaquinta's injury problems on Diego's poor form.

Diego, himself, was struck down with injury during yesterday's 2-1 win over Atalanta.

Zac said: "I think Diego is a trequartista who is good at starting his moves between the lines. He needs strikers who move off the ball and attack the space, plus wingers who push up.

"We saw the best Diego of the season at the beginning, when he played with Vincenzo Iaquinta."
