Jadon Sancho is a good player despite not having a good season with Manchester United but I still believe that if he is managed by a coach that understands how to relate with his players he could end up becoming a big name in Italian league playing for Juventus. Juventus performance is still below average to me despite their performance in the club world cup I think getting Jadon Sancho could boost the performance of the team and his scoring abilities could see them becoming major contenders in the league title next season they need to make sure they sign him to the team.
Although he didn't perform optimally when playing for Man United, his football career record has shown that he is one of the best players and he showed that when he was still playing with Borussia Dortmund, and that is also what made Man United interested in bringing Sancho to Old Trafford. However, Sancho's journey with Man United did not go according to what was expected, but I think this is not only happening to Sancho, but also other Man United players. So I agree with your opinion, if Sancho is in the right team and trained by a coach who understands how to interact with his players, it is very possible for him to return to his best form and shine again.
