Federer is rightly one of the biggest sportsman in Switzerland and his win at the US Open will heighten the home interest in the tie, ... It's fantastic to be playing against him in his own country.
I'm not sure where they're coming from with that choice of surface. I've heard all sorts of things, one of them, which may be a bit far-fetched, is that they've chosen it because they're not sure Federer is going to play.
If you put someone else in to play Federer what would that do to the individual if you had Alan playing or if you had Dave playing. The permutations are endless and, as of yet, I have not made up my mind.
