It's pretty obvious he's referring to that guy from Basel.
dunno, I'm dutch and we have Rojer the doublesplayer, could be meaning him? Or Baker? Or Becker? Berrer? de Bakker? Ferrer?
since I have not really displayed any preference for any of the above, including Federer, I wouldn't know which one it is
the point, which has obviously eluded you, is that he assumes that I'm a rabid Federer-fan, which I am not. Since this assumption leads to simple-minded insults, I really wonder why I am even entering this discu...wait you were right, I'll shut up
