Juventus great Alessandro del Piero says Cristiano Ronaldo still has much to offer new coach Max Allegri.

Del Piero also believes Paulo Dybala must be offered greater confidence by the coaching staff.

He told Corriere dello Sport: "I think that CR7 has entered a phase of his career in which he can no longer do the same things he did ten or even five years ago. He has to adapt himself to his current potential, which is still very high.

“He will need to talk with Allegri and the club and decide if they want to continue together."

Del Piero added: “I would make Dybala feel the trust, obviously if there is trust, and we can't know that."
