Corinthians director Paulo Rosenberg has cast doubt on pursuing a deal for Manchester City striker Carlos Tevez.

Timao marketing director Rosenberg says Corinthians have doubts about the Argie.

"I do not know if the coach believes he needs Tevez or what he thinks of his semi-crazy behaviour," the official told SportTV.

"I don't know if the trainer wants to break the squad harmony by bringing in an unstable Argentine."
