The point of Pre-season is to bring players back into form, players will have been eating a lot more , spending time with families and such so it's normal if they gained a pound. I think we may have had to many friendlies, I don't think this last one is vital, I think the players need some time to rest at training. Even some players who performed in the Euro's have had a lot to do this summer so I do understand their frustration.
But we can still appreciate the effort by Ranieri, he is testing things, and trying to get Juve into shape which is only a good thing. He has overdone it but the man is trying at least.
