Looking back at 2022-2023 Serie A season it showed Inter Milan really focused on winning Champions League which made sense as league title was slipping away. They likely wanted to keep their key players healthy for final even though they did not win it at end reaching final was big deal. Napoli truly deserved their Serie A win playing great all season. There was some confusion about rumors of Conte leaving after winning Serie A but Luciano Spalletti was actually Napoli coach when they won. Results involving Lazio were quite wild those late goals against Inter really affected title race and it was surprising that Lazio could not beat Lecce which cost them spot in Europe.
You made a mistake, it's actually 2024/25 season and not 2022/23 season as you earlier stated. Yeah, Inter Milan gave too much priority to the Champions league and they suffered unavoidable defeats in their domestic Cup game and league games at some point. With all the things that has happened to them in those domestic competitions and them not winning any of it, it will be a relief for them to win the UCL if not it's really gonna be a bad blow to the team and fans in general. As for Lazio, I like it that they didn't make any European competition for last season, it's their payment for not winning against Lecce.
Which would be great, only if it can work again. Conte did started it, but then he left, Allegri took over. So we need to realize there was a problem, and if they can get Conte back, which looks like 99.9% done deal already, then we would need to wait and see if they can do it again. Conte wasn't bad anywhere he went, he was always a decent manager but he is also a little mad, like cuckoo on the head, so it is not easy to keep such a manager.
For example, he left Osimhen out of the squad, because Osimhen couldn't decide to leave, where to, and his salary, and basically Conte just said "you are out" and left him out. No other team would be like Napoli and go "well he must know something we don't" and let him do that. Imagine leaving Vlahovic out of the squad, he would be at risk of getting fired by game five.
