This season, Allegri has shown positive progress in Juventus' performance and indeed for next season they must be able to perform much better than this season to be able to compete in the UCL and all of that does not depend on Allegri alone, but must be supported strongly. by Juventus management to be able to bring in quality players.
I think it is not only Allegri who is responsible for Juventus' unsatisfactory performance, but the entire Juventus management must also be responsible.
I don't see any promising performance from Juventus in this season and Allegri seems failed although have been success make Juventus qualifying to Champion League next season. Actually Juventus get benefit with Serie A has extra quota for participating in Champion League and current standings just remaining four points from Bologna has one match left. I doubt with Allegri tactician in this season will make Juventus finish on top fourth standings position after being draw against relegation team Salernitana on last match.
For next season, Juventus will appearance in Champion League and must improving their performance behind have several years not participants in the highest of European competition. Not only must promising performance in Champion League but also Juventus need return to Scudetto race after missing almost four season.
