The issue with Enzo Maresca is that he doesn't have the mentality that he can pull up good results from the kind of squad he is working with. The mentality is just too average, and it is one of the reasons why they have not won a serious team under his role as Chelsea's coach. he might have helped the team get good rhythm which has made Chelsea have a lot of possession in the games they have played, but that is just not enough. one thing with pochetinho is that it was clear he has a target he was looking out for, the boys where getting better and you could see the boys loved playing under him. Enzo came in with a two-team strategy, which worked for a while, and when injury came in, he is now struggling to get things right for them. If by the end of the season, he can't at least get a Champions League spot, all their effort at the start of the season will automatically.
I don't know, I think he has a great winning mentality, he worked with Guardiola and knows what it means to win, and he won the Championship with Leicester, which is not easy either. I think he knows how to make a good team, but he needs to learn how to pick the right players for it, he did it better at the beginning, now it's clear that he needs to change players in some positions again, it's a constant process, and Chelsea has money, if he gets money for new transfers, he can make the team better.
