Italy World Cup winner Marco Tardelli says Cristiano Ronaldo has been a negative influence on Juventus.

Juventus clinched their eighth successive Serie A title at the weekend, yet most of the talk in Italy still revolves around their Champions League exit at the hands of Ajax.

Tardelli, who played for the club betweeen 1975 and 1985, making 259 appearances and scoring 35 goals, said: "Juventus need to work on managing the squad.

"Maybe Cristiano Ronaldo has played too much this year, but he is the one who commands. Against Ajax he could have done even more.

"Some players give less playing with Ronaldo and, subconsciously, suffer playing alongside him. Dybala is one of those players."
