Emery was hard done by. The board overruling his Zaha signing in favour of Pepe and the the same motely crew of players that got Wenger sacked was what done him in. He didn't have enough transfer windows to get rid of the deadwood. Bar Leicnstiner who was only squad filler anyway all his signing were great and brought the needed grit and steel to the squad. Insanely those players, Torriea and Gwen were booted out by Arteta then.
