Grealish is an interesting example...
The theory is, he left to play for the best team, win things and be coached by the best. The question is ..why?
Why did he leave his boyhood club?...
Is "winning" the only thing that matters?
Is earning even more obscene amounts all that matters?
Is one coach that much better than another?
Is it worth going to a team where you will play less minutes?
Is it worth going to a club that isnt who you support?
Is it worth going to a club that you must acknowlkedge see you as a part of the machine and only a value in $$
Loyalty is inside you... and if it can be destroyed by simple greed it doesnt really exist.
