I see Juventus declining in performance and this shows in their performance, and the position that they are on table. I don't see why you are praising them, that they did well. This is the same Juventus that was having just few points gap from Inter, and now they did not just only lost points, they have been dragged down by Milan to the third position.
Milan does not have a problem, because they started the season well, not until Inter defeated them that they stated having little challenges with their matches, but look at them now very strong and productive. Juventus should be the one that needs to be consistent with their matches, so that they can be able to secure a spot in UCL next year because Bologna is 7 points behind them.
Juventus do not have greater motivation after they are so far behind in points from Inter Milan and in terms of quality Inter Milan is quite difficult for Juventus to compete with this season so we can see that they are playing as if they have no motivation anymore.
And what Juventus is experiencing is inversely proportional to AC Milan which has found its best performance again at the moment. In fact, to compete for the Scudetto, I think it is no longer possible, but Milan can at least finish in the best position and so can Juventus, I think these two teams are still enough. It's safe to finish in the top 4, so for now both teams don't have any pressure.
