yes perhaps you're right.Maybe in 15-20 years! For someone who thrives on being surrounded by players and coaches 24/7, international management is not the role.
The last point is the key bit. Ego. No Brighton manager has backed themselves and their style like De Zerbi. If Chelsea offer, he may stay, he may go, but he's one of the few managers out there with the stones to make it work at that carnival of a club.RDZ will have the pick of the top jobs in football in due course. Why would he want to derail his career at Chelsea like so many others have done?
