The team is in much better shape now, looks defensively much better and is creating far more going forward, despite Vlahovic missing recent games. I think the 352 formation has helped and the consistency in terms of always using it as opposed to constantly changing the formation.
Kean is often disappointing, but that is a great finish for the 1st goal, and a great assist too from Rabiot who has also often disappointed. He's been much better this season.
The better teams are being beaten again too which gives me further optimism. Allegri has shown he should stay for this season, although I need to see more evidence that he's the man for the longer term. The European performances will be key in that as the Champions League campaign was so bad.
