Fellaini just lost his mind. Picked up a yellow for dragging Aguero down to stop a counter attack. Literally 15 seconds later, he does it again. Before the ref has a chance to pull out the second yellow, he headbutts Aguero (one of those where the players are going to be face to face but Fellaini made a motion towards Aguero's head and Aguero sold it) and gets a straight red. Needless to say, it wasn't the best 30 seconds for him.
