He was struggling from the second game of the season, said Ten Hag. He returned for a period and then picked up another injury, so of course that's not great.
Football is about co-operation, says Ten Hag. Finding the spaces by movements, by moving the ball and bringing players into positions where they can attack opponents or get into one-on-one situations.
Aaron today was training today and then dropped out so I don't know at the moment where he is, the diagnosis. Hopefully not too bad, said Ten Hag. Mason and Ty aren't ready.
