Juventus coach Alberto Zaccheroni has warned Diego over his strop against Ajax last week.

Diego reacted angrily to being withdrawn for Mauro Camoranesi on Thursday, and Zaccheroni has warned his players they need to understand that his decisions are taken on what is best for the team.

"The others must understand that we are a team," he continued. "I'm not the coach of the individual but the group and I make my choices based on what is best for the team."
