Mate, although i think the boy can do a decent job on the right, i dont think we'll see the best of him there. In fact, if Rafa uses him on the right, he should get a wooden spoon on the head.
being a RM these days is real tough work. You are expect to defend, cross, get into the box. Spearing strikes me as a Mascherano sort of player, breaking up plays and giving the ball to the players who can use it better. Putting him on the right will just screw up his confidence.
right now, only robocop Kuyt and Gerrard can do all of those things stated above.
