Just the SF and the F could be tricky matches. A match with Stepanek could also be difficult giving his style. But I think he is going to take the title
Yeah, I'm not expecting Mahut/Harrison to cause a lot of problems. Either way, I think we'd all agree that more important than whether he wins Sydney or not is that he is in good form for AO. He needs to start having a more consistent impact on the biggest events and regularly compete for the title.
I think that especially if he's drawn in Nadal's half of the draw he has a more than decent chance to make it to the final there. At the very least, he needs to play well and make QF-SF though.
