Allegri ?
I definitely don't think he will be a good option.
- First he starts by being too defensive, coward so the team has difficulties to attack. During the games, he is waiting too much time to make the offensive subs when they are needed.
- Then, he leans on a big and mentally strong defense, more than Simeone. When Chiellini and Barzagli are bad or face direct attacks, they conceded a lot of chances. The defensive players are like more important than the tactics. So he probably needs to change all the defensive front apart Kolasinac
- Plus, i don't get the "he punches above his squad weight". It's probably the case in 2015 when they eliminated Real and did a great match against Barca but since, he has lost against any better side he met: Bayern in 2016, Real in 2017 and Real again in 2018.
- Finally with his mentality: "i create a defensive plan and let the creatives be creative" he won't improve the offensive side, the lack of movements... and would need some big players, again. For a long term, no need to dream about a transformation into a offensive team because he is stubborn
Anyway, nothing sounds like a start of a good idea
Ancelotti is interesting to manage big teams - not the case of Arsenal and win cups, not to compet for a top 4 of the league
Enrique ? Far from being sure.
Sarri is the opposite of Allegri. Too obstinate with his football pf position. It is beautiful but nothing more.
The others are inexperienced
Tuchel and Low would have been such perfect. Well there is still Jardim
