my goodness you're an idiot guy. have u ever witnessed him have trouble trying to use his left foot? have u ever heard him say i dont have a left foot? i think you're just dumb. He clearly has a left foot but chooses to use his right because he is a righty, just like giggs would choose to use his left 99% of the time. That however doesn't mean they dont have the opposite foot.
he has never been forced to use his left foot yet and has been able to cope just fine using his right, i dont see a problem here. Nani has a left foot too and he does try to use it, and look at the results, he scuffs every lefty shot he takes, just because he feels the need to make use of his left foot. So, do u want to see valencia doing hte same thing? or do u want to see him continue with what's working so well for him at the moment as is turning him into a top class player.
Again i have no idea where this nonsense came from about valencia not having a left foot, totally not true.
