I took it as him saying it's his country and he would play for anyone managing it regardless of whether he respects them or not. As in "my country" is so important to me I'd play if a turkey was in charge. Or "sure of course I love you, you're the mother of MY children.....". I don't think he was implying sole ownership or that it wasn't Mick's country.
But maybe I'm giving him the benefit of the doubt. I always picked 16 as my squad number. Mind you i was often given it by default as I sat on the bench most weeks.
