BBC Radio 5 live sports extra

James Allen and Allan McNish will be live on BBC Radio 5 live sports extra at 11:55 BST, with Jennie Gow reporting from the pit-lane. If you missed last night's show, you can listen to the podcast here.

So who is your tip for the title and why? Does Lewis Hamilton deserve it courtesy of his 10 wins to Nico Rosberg's four? Or should Rosberg's impressive consistency - he's finished first or second 14 times this season?

If Hamilton misses out, where did it all go wrong or what could he do differently? The same questions apply to Rosberg.

"The controversial decision to award double points means all sorts of statistical anomalies could come true over the next two races, and most of them make unpleasant reading for Lewis Hamilton. He already has 10 wins to Nico Rosberg's four, which means potentially Hamilton could potentially lose the title despite winning double the number of races of Rosberg. Equally, were double points not around, Hamilton would need to score only one more point than Rosberg this weekend and he would be world champion. Hamilton has a matter of fact attitude to it. 'What is fair?' he said 'It's the same for everyone. this whole double things has always been a question. It is the way it is. I don't really know what to say about it.'"

A good performance this weekend, then, is a MUST for Nico Rosberg, his title hopes hanging by a thread. He'll have a chance to start on the right foot when first practice kicks off at 12:00 GMT, with the session lasting 90 minutes.

A second session will follow later on at 16:00 and also last 90 minutes. Tomorrow, we'll have one more session of practice for good measure - that'll last an hour - at 13:00 before qualifying at 16:00. And then it's all about the race (16:00) on Sunday.

Grab your diary and pencil it all in. It's going to be busy one.

For a long time this year, it looked like 2014 was going to be Nico Rosberg's season. As the German quietly racked up the points, his Mercedes team-mate Lewis Hamilton was making mistakes and suffering from poor reliability.

But that all changed at Spa when Rosberg turned in on Hamilton. The Briton's tyre was punctured and he ultimately failed to finish the race. The incident sparked something inside of Hamilton, a fire that was stoked inside his belly.

From then, Hamilton has won every single race - five in total - making Rosberg look pedestrian in the process. The result for Hamilton is a 24-point lead, the momentum and a team-mate whose confidence has taken a battering.

"Brazil is in the middle of a severe drought and in Sao Paulo it is the worst one for more than a century. Water supplies are so short in the city that many homes have water for only a couple of hours a day. So the weather forecast for the Brazilian Grand Prix, with thunderstorms predicted for Friday afternoon and Saturday and showers on Sunday is a welcome one for the Paulistas. Interlagos always tends to produce a good race, and rain only intensifies that characteristic. Lewis Hamilton, with a 24-point championship lead to protect, says he does not mind either way. 'When it rains, it always makes things harder but it's really exciting,' Hamilton said. 'I feel much happier in this car in the rain than last year's. It looks like it's going to be a wet weekend. I hope it's dry for the fans because they sit out but I feel confident whether it rains or is dry we can be strong."

There's been disobeying of team orders, ruthless defence of position and clashing of carbon fibre as Lewis Hamilton and Nico Rosberg have fought a private battle for the world title in their silver Mercedes.

It's been a rivalry Formula 1 has dreamed off since Alain Prost versus Ayrton Senna in the late 80s and early 90s. Rosberg, Mr Consistent, was the frontrunner early on, but the second half of the season, Hamilton's raw talent has shone through to gift him a 24-point lead with two races to go.

But with 75 points still on the table - thanks to Bernie Ecclestone's questionable double points rule - there's plenty of room for another twist or two before this season is out.
