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.
When Chelsea chose Enzo Maresca to be their coach, I think it's a gamble because even though Maresca can bring Leicester back to the Premier League but the story could be different if he managed a team that had to fight in the Premier League, and this will be his first experience in the Premier League as a manager. Obviously, it won't be easy because unlike at Leicester, he will be under quite a lot of pressure at Chelsea because Chelsea is expected to return to the top.
