Oh i agree Wenger is a big part to blame in this. His Loyalty in the club and Belief in his players are his biggest flaws and things that have let him down the most.
He needed to be more like Jose a bit more ruthless (and i'm not Jose is biggest fan). Also Wenger seems more interesting in creating then winning. imo Wenger leaving will acutally do him good, i think he needs a new challenge and if he went to a juve say might be the right team for him to get that winning hunger back.
Arsene and Arsenal used to be good but not anymore.
