Marouane Fellaini was sent off late in tonight's Manchester derby at the Etihad Stadium.
Belgium international Fellaini forced his head towards Argentina ace Aguero who fell to the ground, prompting referee Martin Atkinson to brandish a straight red card.
United had to play the final 10 minutes of the contest with 10 men but were able to force a 0-0 draw with their local rivals.
Jose Mourinho reckons Aguero made the most of it and threw himself to the floor, but surely Fellaini should have kept his big bonce to himself!

Mourinho: "it was a red card because it was Marouane Fellaini."
No José, it was a red card because it was a headbutt. pic.twitter.com/7SoCUqOlZV
