Compared to how effective he has been in recent weeks he was very quiet. I agree Zouma was not our best player as i felt Matic and Terry and Hazard were exceptional, but he was very effective.
He was winning more but today he didn't not because of Zouma but because he had to deal with many players who are excellent in the air. Zouma for most part was a non entitiy, was only seen when he pushed Fellaini from the back, won the ball and won the throw in later. He won 1 aerial duel in the whole game.
