Listen, if McGugan was half the player people though he was he would be in the team if his attitude was even half decent.
Abdi was frozen out and forced his way back into contention, Carlos even publicly praised his change in attitude right be before reintroducing him to the side (I happen to think that was a mistake and a catalyst for us going on this bad run. Abdi is a very talented player but I don't believe he's right for our side and how we get our best results).
McGugan could have forced his way in if he wanted to, he has had trouble everywhere he's played, though yes he has the ability to be of some use if he's not willing to earn his place and sacrifice his personal preferences to serve the greater good he can rot for me.
