Yes, that's when people massively overreacted because of his composure on the ball. He's a very good ball-carrier (though much more likely to stumble, trip over the ball and gift the opposition a chance than Evans) but his passing has always left a lot to be desired. This thread is probably worth a read if you can cope with the bar charts and stuff (I couldn't)...

He did one of those "Smallingbauer" half-roulette's too. He just decided in that second half that he's going to remind everyone he's a ridiculously good footballer for some reason. Someone made the point that Fletcher started sitting back in almost on top of the centre backs after 60 minutes and I reckon that must be it - Fletch was wrecked so Evans and Rio took turns doing his job while he dropped into centre back. Can't remember the last time Rio played like that.
