Milan was indeed lucky to win Juve and qualify for the champions league next season. If it wasn't for Juve's point deduction,they would have be among the top four. I think next season will be a good season for Juve both the problem that they will have is that some players might leave the club due to their zeal to play in UCL. Milan will perform brilliantly in the champions league next season and I hope to see the best in them. Juve performance this season was good and they could maintain their quality and still finish at 7th position.
Yes, Milan should have no hope of finishing in the top four, but because of the penalty for Juventus, everything is different. Uniquely the Rossoneri were also able to win at home to Juventus where they successfully locked in the top four of the standings.\
For next season, it is certainly difficult to predict who will be the best, because almost all teams will evaluate their respective teams. I think it's too early to judge the team's prospects for next season.
The next season of Serie A will be even more crowded. This season we have only seen the dominance of Napoli. No other team is fighting for the title. Napoli have maintained their dominance since the start of the season. And they won the title quite easily. But next season Inter Milan, AC Milan, and Juventus will try their best to win the title. The team's performance was very erratic this season. They will strengthen themselves in the coming season. And so the upcoming season is expected to be quite busy and exciting.
