I actually think Misha is even better on fast surfaces than clay, although his results on clay were better.
I don't think we will defend the title although I obviously hope we will. I think we'll get through Czech Rep, it won't be easy though. But Argentina will be too tough IMO, at home they play better, the support there is tremendous plus they'll be eager to get revenge from this years loss. If we get through Argentina, we have a good chance to win the Cup, esp if we play the semi and the final in Moscow
