Everybody knew the post-Arsene Wenger transition was going to be difficult, but nobody quite appreciated how difficult. In a sense, Unai Emery was given an impossible job, handed a mismatched squad that had been allowed to drift as football moved beyond Wenger’s methods with a chaotic management structure that seemed to lose a key part every couple of months. Communication, though, was a major problem, as it had been for Emery in both his previous jobs outside of Spain. The media often had no idea what he was talking about and neither, various players revealed, did the squad.
