Anyway we need to see what will happen this week, The Champion's League starts.
Compared to their performances in previous seasons, I'd say they're doing poorly lately. 1 point in 3 matches is a very poor performance in my opinion. Ronaldo leaving the team didn't help them one bit as they were still struggling even while he was around. With the way things are going, they're in serious trouble this season. Roma, Napoli and Inter are doing much better.
Juventus will almost certainly finish 3 or 4 this season, they won't be able to win Serie A and they won't even go far in the Champions League.
