Allegri could not deliver what was expected, especially in the last 2 months. Juventus, who had lost points in almost all of their 2-month matches, was on the field. I expected a better performance from them this year because they had the opportunity to rest more while their opponents were tired by playing European matches. They failed again and I think Allegri should quit team now.
The Juventus team management has to evaluate this from now on or when the season is over, because as you said, at the start of this season Juventus also looked good before conditions like now happened to them. And if the team really wants to remove Allegri from the Juventus team, the team must first look at a replacement with greater experience so that they can bring Juventus to a better level than this season in the future.
Allegri has done his job well and the decline in performance since the second half of this season may be a little reasonable, but I see that Juventus' overall performance is much better than last season, so if this progress continues, it is possible for the Juventus team to develop further next season.
Allegri really understands the Juventus team because he has been quite successful with Juventus in the previous few seasons, but currently the team's condition is in decline and I think that's a normal thing for a football team to experience.
