Only thing I've ever seen him do with his right foot is use it as his support foot, using it to place the ball where he wants it etc. I haven't seen him shoot, pass or cross with it. Then again, I haven't watched him a whole lot, I must confess. I'm just hoping this is true.
I definitely don't mind that he uses his left foot 99 % of the time, but it would be comforting to know that he can use his right foot as well.
