Fellaini is retarded, no need for that at all, with very few Liverpool players forward just run to the box and defend there, he's conceded a freekick that means he has to do that now but against more Liverpool players, there was really no direct danger and he set up a much more dangerous situation instead.
The pass by Fellaini a minute before was Evans(i think it was him) fault, it was into the space and had the other player run on to it he'd have got to it first, ridiculous decision to ignore it and stay back.
