If that act of petulance makes him "a self centred unprofessional ****" then what's the difference between Aguero elbowing Winston Reid for no reason other than him having a bad game, or lashing out at Luiz?
Aguero, who also, according to his former teammate, arrives late to training often and gets more fines than anyone else at the club, things which I'm sure you'd be frothing at the mouth about if Nasri did them.
