One way to look at it: They chocked us in midfield. Back four had no one to pass the ball to, so Silva, Nasri and Yaya had to retreat to receive the ball and end up stuck there. Their strikers put on a great shift chasing and breaking our play before it started. They played to draw, we should have sat deep after scoring the first goal and let them come out. This would have open them up. Issue is, when you have Nasri and Bony on the field, forget counter attacks.
Other way: Our tactics were spot on. We are just shit at converting. 3 glorious misses. That Bony slashing the ball was embarrassing, and so was the frail attempt by Sterling's in 2nd half. Had any of the three chances were converted, the game would have been put to bed. Juv got very lucky with their chances, their two goals were so borderline, both hit the post to get it. Either brilliant aim or luck.
Either way, its our fault, Nacho should have started ahead of Bony and KDB ahead of Nasri. This was obvious to many of us when teams were announced. But we don't know the exact situation with the players better than the manager.
