Juventus' weak point was attack, which is why they even used Chiesa, a nominal midfielder, as a striker, and Vlahovic was not enough, the team needed a good striker, but Alegre could not get enough funding for this. They tried to sell Vlahovic, but they didn't succeed, in the end I think that this was the main reason for such an uncertain season for Juventus. Alegre built a good defense, he knows how to do it. I don’t really like how Motta is rebuilding the team yet, I want to be wrong because I like Juventus, but I doubt that Juve will have a chance to compete for the Scudetto in the new season.
Juventus' weak point was Allegri's terrible defensive tactics that suited no one in the team, and they had absolutely no build-up play whatsoever. Juventus traditionally has strong defenders, but they were always able to supplement that with quality midfielders who knew and had the freedom to play football. That wasn't the case under Allegri. Chiesa is a left winger and good as a second striker. When healthy and under the leadership of a good coach, he can contribute with around 10-12 goals a season and around double-digit assists. Looks like we won't witness what could have happened under Motta.
