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.
The question for now is whether it is still possible to do it now? It does not mean that I am not sure about Xavi's performance because looking at the conditions clearly I prefer Xavi over Motta for now when talking about coaching but Juventus in the scheme that they always do very rarely change coaches when in the middle of the season even I forgot when it happened because they sometimes change coaches definitely in the new season.
If indeed they will continue to maintain the old tradition like this then it is quite clear that Motta will still be safe with his current position at least until the end of the season.
On the other hand, Motta's performance is actually not too bad, it's just that he also can't be said to be good for his first season at Juventus especially with a record of 13 draws which mostly occurred in the middle of the season clearly this is a less good record even though for now they are quite consistent in winning every match.
