I definitely say YES with this. I meant replacing Motta with Xavi is very worthy decision for Juventus. I know some might be disagreed, but i personally think that if Motta is already failed in helping the club.
Juventus is not even a competitive compared to the Napoli and Intermilan, though they also spent a lot of money on summer last season.
If Juventus is willing to see its club to be back competitive again, they have to sign Xavi and sack Motta.
There were no contacts between Juventus and Xavi, and Motta is promised that he will remain as head coach next season, so it seems that everything suits them. Although I am also inclined to think that Motta is not the best coach for Juventus, in essence he is no different from Alegre, very similar manners and strategies, maybe the only difference is that Motta is younger and more reserved on the field and in transfer demands.
