BTW, no I heven't met him, Belgrade has a population of >2.000.000. but I heard that he is a really down to earth kind of guy, from a friend of his.
P.S. the funny thing is that when he tried out for a national Club in his youth, the trainer said, nothing will come off him! So he didn't get any National support at all, his family preatty much sold everithing they had and enroled him in foreign tenis schoos.
