BBC Sport’s Piers Newbery Tweeting from the O2 Arena:](http://twitter.com/piersnewbery)“My money here is on Nadal, strangely. He’s fresher and desperate to show some form. My tipping form is about 51% - do I make the semis”

From benny007 on 606:](http://www.bbc.co.uk/dna/606/A60086711)“Come on Novak! I’d like to see him in the finals, especially if he does his infamous impressions!! But a part of me wants to see Rafa win at least one set. Just to prove he’s not really lost it all…”

1425: Nadal and Djokovic have met 20 times before - with the Spaniard prevailing on 14 occasions. He’s not firing on all cylinders at the moment, though, as I’m sure you’ve noticed. But, having said that, Djoko is hardly full of beans himself either. Who will win this one then Your guess is as good as mine but I’m going for Djoko in two…1420: While the players warm up, I’ll remind you lot how to get involved today.Tweet me on Twitter,](http://twitter.com/chrisbevan_bbc)text me via 81111, or drop me a line on606.](http://www.bbc.co.uk/dna/606/A60086711)I’m waiting…1416: Did you know that you can listen to commentary of this match on BBC Radio 5 live Sports Extra You do now - just click on the link on the top right of your screen and you’re away.1415: Here’s Rafa too. “I’ve got nothing to lose,” he says. He hasn’t won so much as a set here this week… time to change that, surely1413: Here’s Djoko, now in his pre-match interview. How’s he feeling “I’m trying not to think about the exhaustion I am feeling, and hope to take my chances in this match.” Hmmm, not great then. You might remember that the Serb was practically out on his feet after losing to Robin Soderling on Wednesday.1410: It’s as simple as this: Robin Soderling is already through. Rafael Nadal is definitely out. Novak Djokovic needs to beat Nadal in today’s first match and hope Soderling beats Nikolay Davydenko later on. Any other outcome, and Davydenko joins Soderling (and Roger Federer and Juan Martin del Potro) in the semi-finals.

1405 GMT: Afternoon folks. So, is your brain still fried from last night’s extraordinary events at the O2 Thought so - mine too. Here’s the good news then: The shakedown in Group B today is an awfully lot easier to understand (and explain), even for an idiot like me.
