Scared is the word Xhaka used. Even if you interpreted it as nervous, it doesn't help. Players do their own thing because we don't have a system. Wenger used to concentrate on our game with maybe not enough attention to the opposition. Emery changes to nullify the opposition, with only the defence remaining unchanged.I don't think they were scared but players need a system they know well enough they can operate on automatic when things get tough . We got so many players that do their own thing .
