I've both supported him, and complained about him on this thread before now, and have deliberately not posted on it since Saturday, as when I did I wanted to do so with a degree of impartiality.
I'm sorry though, he was piss poor on Saturday, pretty much back to the awful Plzen (H) performance (his worst performance in a City shirt).
The miss, ridiculous though it was, was the least of my concerns, it was virtually everything else he did, or more often than not didn't do.
His movement was dreadful, his first touch generally poor, his hold up play was none existant, he had one decent knock on header all game, I don't remember him making a single challenge, he had one decent effort on goal when Negredo laid it on for him, but that, the one header I mentioned, and one clearance in our box, was the sum total of his positive contributions, and its a pretty lame effort for 90 minutes, but the worst thing of all, was that he put more effort into nearly breaking his foot on the post, than pretty well everything else he did, and that was stupidity because we'd already lost Jovetic, and we have Aguero still not fit, so he was risking a really stupid injury, for absolutely nothing, ahead of a cup final, the act of an idiot, frustrated or not.
He's generally played well in recent weeks, so why he has suddenly returned to this, I've no idea, but I hope he snaps out of it quickly. Those blaming the fans for it though are just wrong, the cause is his, not people complaining about him, and if he plays like that I'm afraid he deserves to get some stick.
