When the line up was announced on Twitter, many Gooners were having a fit that Francis Coquelin was starting the game in place of Granit Xhaka. But I think Coquelin was exceptional in the opening stages of the game, he was one of the guys that set the tone he was part of the reason we imposed ourselves on the West Londonders. His injury, picked up close to the 30 minute mark looks serious and could rule him out for a long time. He looked visibly distraught as he limped off the pitch. Arsene has shown incredibly amounts of faith in Coquelin this season when it looked like he may have fallen way down the ladder, we have to hope that the injury is not worst case scenario stuff but it looks bad.
