Cannavaro declared yesterday that Messi made too much of the attention he received from Real defenders during Saturday's big match.
In response, Messi snapped: "He shouldn't worry about me. He should be worried more about his own team and think about that."
The Argie added: "I do not have to ask him anything from the referees. They are there to do their job and try to do the best they can. They must be allowed to do so without other people putting more pressure on them."
