I wonder how much TMac is a key piece to this formation. He seems to drop deep often making it more of a 442, and since Mata pushes up, and Villa drifts left. i wonder if a Harrison type on the left would detract from our midfields ability to get the ball forward.Seems to me that Harrison has a strong grasp on the right wing position. Staying with the NE revolution, I wouldn't mind a Diego Fagundez type player on our left wing.
