wasn't really unexpected. We cant defend and our attack was afraid to shoot from outside the box. Was only a matter of time before they killed us on the counter attack
Thing is, this time you can't blame Flamini or Mertesacker. Not their fault. Arsenal's best defender and maybe the best player so far this year was abysmal today. I'm talking about Koscielny. Can't blame him too hard for penatly, but it was mistake. Class defender would get proper tackle there. But second goal goes on him because he wasn't pushing forward, which would leave Costa in offside.
Edit: Also Wenger is at fault because he didn't say his players to shoot first few minutes after Cech came on goal. That's the best time to test long shot because keeper isn't ready for the game. Szczesny wasn't anything special, but that's him. Dunno why Wenger thinks he's better goalie than Ospina?
Arsenal badly needs one world class defender and world class DM. Rest is fine and with better aproach they can win against Chelsea. Can't tell they were impressive today, were good defensively but that's because Arsenal was impotent with their typical cute little passes and high balls (my blood pressure was raising every time they try to find someone with a high ball). Short players and high balls don't go well together.
