Juventus great Alessandro del Piero says new signing Leandro Paredes isn't enough for Max Allegri's team.

The PSG midfielder has joined Juve on-loan for the season.

After Juve's victory over Spezia last night, Del Piero said: "I don't think Paredes is enough, Allegri must be able to field the team that he has in mind.

"He needs (Paul) Pogba, he needs the best (Angel) Di Maria, he needs (Federico) Chiesa.

"Even today Juve did not play well, they struggled a lot and I expect something more. In any case, Spezia played well."
