Costa, grade A **** as we all knew really. Gabriel, moron for not being ready for and ignoring it.
What I want to know is did Gabriel just lightly step on his foot because walking backwards Costa just stopped behind him or did he actually kick out at him, if the latter I can understand a second yellow card. From the replay it was so hard that Costa literally didn't move an inch he just looked at the ref straight away.
Who will go off, who will come on... Walcott has been dire as a leading man again as anyone who has watched him start through the middle absolutely knows except Wenger. Walcott for Chambers or Debuchy, Chambers was so utterly awful against Liverpool but Debuchy hasn't been much better and you're basically crapping on CHambers if you don't bring him on as CB. Then what upfront, Sanchez has been dire again, Ozil has been asleep, bring someone off for Giroud but again who.
