Juventus manager Andrea Pirlo may struggle for success while Cristiano Ronaldo remains in Turin, says Antonio Cassano.
Critical questions on Juventus re-emerged this week after the Serie A went down 2-1 to Porto in the UEFA Champions League last 16 first leg tie on Wednesday.
Additionally, Juventus are eight points of league leaders Inter Milan after 22 games of 38 in Italy’s premier division.
According to the former Real Madrid striker, Cassano, Ronaldo could be the individual standing in the way of manager’s Pirlo’s success.
"I have always said, even though he is a phenomenon and has scored a billion goals, that with Andrea Pirlo's idea of football, he could run into difficulties," he told Christian Vieri on Twitch, according to Goal.
"He scores a goal per game, it's true, but he struggles with Andrea's idea. He's always been a bit selfish, he doesn't give a damn about others scoring goals.
"He's the kind of player that lives to score, not for the game, for the great match. He lives to score and in this moment the situation is getting worse. The years pass for everyone and he is having difficulties.
"The paradox is that Juventus have bought a player who has won five Champions Leagues, but has so many difficulties in the Champions League.
"This is because, since (Maurizio) Sarri, Juventus are trying to show a style that is different to its history. It's clear that Pirlo must be judged in four or five years, but Juventus want everything immediately,” Cassano concluded.
Up next for I Bianconeri is the visit of minnows Crotone on Monday.
