First noticed this when Wenger switched to a 4141 with Coqblock sitting deep to protect Koscielny and Mertaslacker who were getting roasted by players running through our midfield lines straight at them.

Worked for a time until people figured out they could just go wide or behind our full backs making Coqblock redundant.

Real shame Unai has lost so many players. Thought he was making real progress with some of them.
