Stupid first yellow, correct second, so all in all a deserved and stupid sending off. The annoying part is that Balotelli does this every other match and never gets booked for it. Zabaleta should have had a second yellow, instead he doesn't get a yellow for that first offense, which was twice as bad as what Blind was similarly booked for.
Uncharacteristic of Smalling this, so let's hope he doesn't commit to such stupid bookings again. He's been good lately, so it will be a loss. Both McNair and Carrick played very well though.
