Although it is difficult, the possibility is still there because Chelsea already has a strong enough team framework and also many quality players so it is not so difficult for Enzo Maresca to be able to build this team and compete at the top of the Premier League standings, but the percentage for that is small, I admit that but I see it quite optimistically. Enzo Maresca is a fairly qualified coach, he only needs full support from Chelsea management and even if in his first season he cannot bring Chelsea to the best position at least Chelsea management must be able to give Enzo Maresca several seasons to be able to build the team with the process.
The problem is that Chelsea management still often fires its new coach when there are no good results in a full season as happened to the previous coach last season. So that at least has made Enzo Maresca improve his ability to train all the players in the team better by providing ways that can make the Chelsea team rise next season. However, when the results obtained by the Chelsea team are still far from their expectations, of course Chelsea management also does not need to fire Enzo Maresca at the end of the season as has happened to several previous coaches at Chelsea.
