Great in the first half, absolute shite in the second. Thats pretty much the Arsenal we have now.
however, it says a lot about the referee when the giroud booking wasn't his worst decision of the night. There was a clear trip on ozil, nothing given, the handball he denied us, and the alexis challenge where upon wasn't even booked.
also with the giroud booking, the referee didn't even see it, he had his back to play and only turned around after Giroud started running towards the ball.
