Spalletti over Gattuso at Napoli is an upgrade as well and their squad is a good fit for him. If they manage to sign a decent lb and a midfielder to start next to Ruiz i think they can do well. Obviously they won't fight for the title but i believe they will finish in top 4.
Mou, even this version of him, obviously is an upgrade over Fonseca but they have barely made any moves and they need a squad overhaul if they want to finish in top 4. I am not worried about them just yet.
I rate Sarri highly but he is going to need time at Lazio. They aren't going to be a threat this season.
I am expecting more or less the same from Pioli at Milan. Great first round and an inconsistent second round with the difference so far the squad is actually worse even though they have been one of the highest spenders in Europe.
Atalanta have kept Gasperini and most of their squad. They will probably lose Romero but i am sure they will figure it out. I am expecting them to be in the mix for top 4 again.
Top 4 isn't going to be easy. I would be more optimistic if Conte was still our coach but i have no faith in Inzaghi. The guy got out of his comfort zone for the first time in his coaching career and he is a complete unknown at the top level. There's some pressure at Lazio but let's be real. It's nowhere near the level of pressure he will face at Inter. Especially at an Inter side that just won Scudetto. I hope the guy proves me wrong and he leads us to glory.
