I believe Juventus will be able to improve their performance much more by the coming season. They started to perform better especially after they signed Vlahovic. He made their attacking line stronger than before.
Too early to judge they will improve their performance. The problem in Juventus isn't only about the attacking line, but they also have problems in both midfield and defend lines. So, the problem is quite complicated. Another problem, the players have no good mentality as the winning team anymore. The coach must fix this if Juventus wants to improve their performance in the next season.
Although Juventus' performance is considered poor this season, Juventus have not been out of the top 4 of Serie A for several years. I think it's just a matter of team cohesion, Massimiliano Allegri must be able to restore the confidence of the players. For strikers, midfielders and defenders, that's enough for me. Juventus is my favorite team from Serie A, although Juve's performance has decreased since last season, but I still appreciate the team's solid performance.
