Sinatti said during an interview for AS that he sees the team "far way from what Sarri wants". Their fitness currently isn't good and that is vital. Things aren't working very well. Balls aren't getting moved quickly in attack and defence and the players still aren't working very well. Every player seems to be doing their own thing", he explained.
"I don't know if Sarri changed his work type, but I know in the past his teams performed thanks to their good fitness levels that the players usually had. He added that "at Napoli we have a lot of matches but everything works very well.
Regarding the little changes, which you always receive criticism for, Sinatti also stated that "Juve players are used to playing 60 matches a year. I don't think that it is the problem.. the problem is another thing.
Lastly, he did though affirm that Cristiano Ronaldo shouldn't be overplayed. "He will need to rest at some point. Although he is called Ronaldo he can't always play. The ideal situation is that he should be 100% at key moments".
