Looking forward to Nadal v Del Potro. Would love to see Delpo produce one of his all-action big hitting performances. On the other hand, would be great to see Nadal close in on a sixth Masters title for the season.

Should be a great match!

Novak Djokovic starts his Shanghai Masters campaign on Wednesday against Marcel Granollers. After watching him destroy the Spaniard in New York, I can only see that match going one way.

Novak Djokovic didn't mince his words when talking about the Viktor Troicki doping ban. It'll be interesting to see what happens with Troicki's appeal.

Rafa hasn't been beaten by Tomas Berdych since 2006. I'm pretty sure he'll take the World No. 1 spot on Saturday.

Rafa is one match closer to taking over as World No. 1. I don't think he can be stopped in this kind of form.

Fognini up next. The Italian played superbly against Nadal at the French Open, but even that wasn't enough.

It's a shame that David Nalbandian has had to retire. The farewell tour with Rafa should be interesting though.

Na Li is in great form in Beijing and I think she'll get the better of Sabine Lisicki. Could be a tough one though - Lisicki was superb against Venus Williams on Tuesday.

Will be amazed if Rafa isn't No. 1 by the end of this week. He's been unstoppable on hardcourts all year.

Don't expect Santiago Giraldo to beat him on Tuesday!

Very surprised to see Joao Sousa win the Malaysian Open. Can't be the same guy who looked like a part-timer against Novak in New York, can it?

Serena begins her China Open campaign today. It's been a long season for her and burnout could be an issue, but can't see her slipping up here.
