Juventus great Fabio Cannavaro has questioned the decision to re-sign Paul Pogba.

The former Manchester United star put an end to his second spell at Old Trafford by returning to Turin on a free transfer following the expiration of his contract this summer.

But it wasn't long before he sustained a knee injury that ruled him out of action.

Cannavaro is concerned about Pogba, claiming: "As a football player Paul Pogba thrilled me a lot. But in recent years living at Manchester United he was unrecognisable.

"Treating him in excess of his hair and image makes me suspect that he feels he has arrived.

"And when a football player thinks like this you can't compete at the top, 100 per cent. But I am convinced that he wants revenge in his second life in Italy."
