He's much more dangerous around the box on the right, imo. So quick, great at feinting as though he's driving right, stops on a dime, and either whips in those great in-swinging crosses, a short incisive pass, or rips a shot. It seems to open the field up for him.
The guy loves to cut into the middle, around the box and in transition. Because he's so left footed, as soon as he moves into a more central position with the ball, he's got very few angles available for forward passes. Again, from what I see, playing on the right opens up the field for him. He's more comfortable over there.
Unfortunately, Cuadrado and Bernardeschi are also more comfortable on the right. Bit of a logjam at that spot.
