You're reading what you want to. IMO, he played well, then drifted off and turned into a sad little puppy wandering about with that frustrated look on his face. And once you see that look, you can be sure he won't be doing much. And he didn't.
Of course, you can and will blame that on the defense, or the mid-field, or whatever else you want to. I saw a player who was taking too much time on the ball, not passing to others and unable to get his head on the ball. Tale of two halves. Second one was shit - but again, nothing to do with him in your opinion. In your world, he was a 10 running around amongst a bunch of 5's. Is that is?
Is that what your obsessive nonsense is about?
Or could be have fallen off a bit as everyone in the world seems to think but you?
