In fact, it's not about the arms, it's about the shoulder. You gotta turn more the torso and point the shoulder to the ball more. Good pics and you seem better than Xristos. (well, it's not a big deal, but... sorry).
That will be the last victory of Rafa for quite some time.. With his joke mentality and pathetic game, I hope the disgusting player loses every single match next season. He's disgraceful. He should just retire. He's a joke.
