If you see Enzo Maresca (44) as not a young and dynamic manager then I understand.

But I think he shouldn't be considered as an old manager where Xabi Alonso (42) is also considered as a young manager.
I see managers at the age of over 50 as old ones. For example Conte (54) would have been like that if Chelsea contacted him. Anyways,
Fabrizio Romano has already announced the agreement between Chelsea and Enzo Maresca. I'm excitedly waiting for what is going to happen. He has an experience as an assistant manager at Manchester City as well. He must have learned some good things from Guardiola. Making Leicester win the Championship is a start already.

I have noticed a trend that now coaches who have ever worked with Guardiola are highly valued (Kompany - Bayern, Maresca - Chelsea), and if the first one is quite young and has not yet proven his skills with impressive results, then Maresca was able to win the Championship, which looks very earnestly. He is already discussing summer transfers with the management, for now it is reported that he wants to buy a goalkeeper and a defender.
Yes, many teams are feeling that these coaches will do the same as Arteta of Arsenal since they both have similar training as him. Vincent Kompany played under Pep, whale Enzo Maresca was his assistant at Manchester City before Joining Leicester City.
Bayern Munich and Chelsea are looking for young managers that will bring fresh tallent to their teams because they have signed old managers and nothing worked for them, and the success Enzo had a Leicester City is what convince Chelsea to go for him, while Bayern trust Kompany with his tactics despite been releated from the Premier League this season.
I wished them the best as they all take up new responsibilities.
