Former AC Milan coach Arrigo Sacchi has questioned if Juventus can handle Cristiano Ronaldo's ego.
The former Real Madrid star completed his move to Juventus yesterday in a €112m deal.
"We were not used to having the best players in Italy and Ronaldo is perhaps the best, he is probably among the two best in the world," Sacchi said.
"Congratulations to Juventus, this operation will be good for Juventus and Italian football.
"The only doubt I have is that Juventus have always had a great leadership as a club, the salaries of the players were different but the rules have always been the same for everyone, this has to happen with Ronaldo, otherwise there could be problems inside the dressing room."
