Allegri will put Milan back in form in order for them to bs able to win Seria A, because he knows what to do. He is used to Seria A and has proven to be a good coach in the past. He has gotten more experience overtime and that gives me much confidence in him. I hope to see Milan in their best performance next season.
Yes Allegri can bring Milan back to winning Serie A and for good reason. He is highly experienced coach who has already won Serie A title with Milan in 2010-11 and then dominated with Juventus winning five consecutive league titles. His success comes from his adaptable tactics and along with his skill at managing players and adapting to different opponents all of which Milan needs for consistent top performance. While Milan has shown flashes of brilliance they have lacked consistency and your hope for Allegri to provide leadership and mental toughness for them to finally win Serie A title next season is reasonable one given his proven ability to build winning teams.
All of this team's performances seem muddled to me, and I don't see any sign of any significant contribution from their coach Allegri. We observed that this team managed to win a final match against their city rival club under the previous coach but the way they have fared in their domestic league this year, it would never have seemed like they had been able to win 19 titles in this league before. You correctly stated the view that his success will come from adaptive strategies and skills, I think the iconic players of this team and the Italian giants with so much success are one of the most famous revolutions in the world of football because they also own so many titles.
It's true that Allegri is a good coach that can bring milan back to winning ways but the fact is that you don't expect things to change in Milan just like that because this current Milan team is lacking behind in quality in so many ways so Allegri focus should be getting a good team that can be competitive in the league
