I was thinking the exact same thing while I was reading the thread. He was out on his feet.
if his fitness is anything like last week, I will be stunned if he lasts 90 mins on Thursday and I would say there is next to no chance he starts on Sunday. Cant go from playing 75 mins in 6 months to playing two games in a week.
Not saying he is or isn't committed to playing for Scotland, but what I saw from him last week and the fact the Arsenal medical staff told Emery that he couldn't travel to Utd on Monday to sit on the bench, shows he is nowhere near fit as he needs to be. If that is the case, then what is the point of him travelling to Russia? He is better off being monitored by the Arsenal medical staff to ensure his rehabilitation is managed properly.
