A 33-year-old Arteta is a better player when fit. You guys are going crazy. He only plays one side of the game! Wenger had to change around central midfield to accommodate his weaknesses. He had a good spell and will remain an important part of the squad but his inability to get involved in possession has slowly revealed itself, and we can't have a starter with those limitations if we're trying to win the PL. Alexis and Özil had to receive the ball very deep when Coq played, which makes it harder for them to do what they do best.
Coquelin has a ton of interceptions and tackles, yes, but part of those huge numbers comes from our inability to control central midfield over 90 minutes.
