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.
Guardiola is a very talented coach and any one thag trained under him will surely have gained a lot of knowledge from him, Arteta, Maresca, kompany are one of the managers that have worked with him and they must have learned some BBB few things while working under him so i am not surprised when they start exhibiting some talent. Arteta have shown the world that working with Guardiola was worth it and now is leading Arsenal to one of their best seasons ever, no trophies won yet but i believe soon they will win something.
Chelsea’s choice of coach is really good i just hope they will be patient enough with him if things doesn’t work out soon enough.
