You guys say he is a proper RB but he scored with his left foot in that youtube clip (I only noticed cos it reminded me of a goal I scored - I'm a natural leftie - although mine was more looped, no defenders came out to pressure me, and Buffon wasn't in goal...).
And apparently that was his first professional goal according to wikipedia. He can play LB too, my guess is that this guy is a natural leftie from that amazing goal, no way can a defender score like that with their weaker foot...
