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.
I don't think Juventus replacing Thiago Motta with Xavi would be an upgrade. If Juventus wants to reclaim their crown back in Serie A, they need a coach with a proven track record of success, someone that is capable of improving both their performance level and their style of playz While Xavi might be under consideration, I don't believe he possesses the tactical ability and experience to achieve such a feat especially given the highly competitive nature of Serie A.
When you say manager with track record I trying to understand what you are talking about. Because if you are saying that Xavi has no track record, I think you are joking. Xavi was exceptional during his career as a player and as a manager he has won silverwares. Or have you forgotten that he won the league when he was the manager of Barcelona? He also guided Barcelona far in the champions League when he was there. The challenges he had with Barcelona management was that he wasn't ready to work academy players, when it was obvious that Barcelona were struggling financially. He wanted to be backed with funds so he could buy players of his choice in the market, which wasn't coming forth. Tactically Xavi is up there and if appointed by Juventus he will do well. How many managers in the Seria A is better than Xavi in terms of what they have won as a manager?
