I agree it was possible they had none willing to take the job but I'm not convinced they tried. Moving on to Nice is a step up the ladder of league quality but they're still assistants. I find it hard to believe a shot for one of them to be the head coach of NYCFC isn't equally if not more enticing. I don't think CFG even considered it they wanted another MCFC guy.
CFG considered no other candidates. Dome was expendable.
