Lazio great Paolo di Canio has one doubt about Angel di Maria's move to Juventus.

The off contract PSG winger is set to sign for Juve over the weekend.

Di Canio told Sky Italia: "He is an outstanding, fantastic player. He was probably the only PSG star who gave everything, helped defensively, fell down when needed.

"It will be exciting to see.

"But I doubt one thing. I understand that he's only coming for a year. You know, it's the World Cup ... he does not back down, but when you are part of the project and sign a long-term contract it is different."
