Changing coaches may be a major problem because they do not match the strategy given by the new coach which ultimately makes the players play not according to the rules and not according to the instructions or directions from the coach so that the lack of teamwork that ultimately makes Juventus often get a very embarrassing defeat. Usually Juventus will follow the movement of PSG and match their game but it seems this season they are not able to do that.
Juventus need to learn from Atalanta, because Atalanta have kept Gasperini since 2016 both under difficult circumstances and when they enjoyed the euphoria of playing superbly in the UCL and snatching 3rd place in Serie A in several seasons. Sometimes patience will pay off. Likewise with AC Milan, although Pioli is not considered to be successful in giving the title, in fact he can prove it.
