Motta has shown that he is no more effective than Alegre was, too many draws, the team still has the same problem that it had, their attack is weak to compete with Napoli and Inter and even weaker teams. They will not get the Scudetto this season, even if they can take points from Napoli in this match, it will only give an advantage to Inter, who are on a very good run. Juventus should think about strengthening the attack, or about changing the coach who will insist on this more than Motta.
I also see it the same as you that Juventus does have a pretty good chance to be better but I think Motta just wants to maintain the performance that Juventus has had so far, a draw is an option because their attacks are not that effective in attacking stronger opponents or when playing against weaker teams, against Inter Milan and also Napoli of course it is very difficult for Motta, changing coaches I think it will take more time, and the big question is who is the right candidate for Juventus, sometimes we think it is better to replace, but the matching process will be very difficult and takes time to adapt to the TEAM.
Draw that many games require some talent too, they are really doing a wonderful job and I am pretty sure that while they are unhappy with the results, they are happy to be decent, and they are not unhappy enough to fire him just yet, they are doing decent enough to make him keep his job. Of course how the season ends matters too, they have no loss so far, which is a great achievement, and if they can end the season without losing, or just lose few, and win most games instead of get a draw, then we could see them finish in top four, and that would be awesome for them.
Of course this is going to take a while, and it is not going to be easy, but we could definitely see this as a big win for them. Motta isn't a bad manager, we have seen him do great before, and I am sure that he is going to figure out a way that he could make them do better again, they just need some wins back to back to be great, and they could make that happen if they play just a bit better on offense.
