I'm actually hiding my emotions, in real life I would be shouting at the OP.
I don't understand why people keep making claims like "they are downing tools!". We are talking about players that have for the most part next to no track record of success, most of them
have extremely obvious footballing flaws whether we are talking about athleticism, technique or decision making. They didn't decide to not be elite just to spite a manager, managers who by the way were/are themselves far from elite.
Also let's be clear about something mental fortitude is part of being elite, it's not something that you control, it can be ingrained in you by tutors during your formative years but you don't switch it on and off.
