Imo wenger is harming that team in double ways.
1. He has lost it when it come to team selection, lacazatte on bench, players not playing at proper position, not understanding the opponent strength like going 3 at the back against 3 of Liverpool's front 3. The list can go on. Same tactics whether its liverpool, stoke, Barcelona, champions league, home, away ..no change.
2. Players like ozil and others are getting no criticism, because wenger is having all the blame and deservingly so. But that gives a free ride to players. You go on their fan tv or forum and all they talk about wenger nobody says anything about players. I dont think klopp would tolerate that sort of desireless display from any of our players.
