This week, it's all about the drivers making their final preparations, and having their final break before the back-to-back races to finish the season. We've had teammate announcements and disappearing drivers, but in terms of the rankings, it's all about training and tweeting, posters and hashtags.

After this week, there are just three more weeks of Rankings to go, when we will crown the winner of the 2013 title. Make sure your favourite doesn't miss out by sending across your suggestions for points - but don't forget, they can go down as well as up!

Movements for Week 39

• +1 Lewis Hamilton: Sending Vettel a nice congratulatory message/challenge.
• +2 Felipe Massa: Getting up to some pranks with good friend and fellow Brazilian, Rubens Barrichello. This time, photo-bombing a sleeping McLaren driver.
• +1 Fernando Alonso: Celebrating the upcoming trip to the US with a bit of a TV series poster. Anyone seen it though?
• +2 Romain Grosjean: Indulging in some rather different training - beats all the cycling and running drivers normally do!
• +2 Jenson Button: Getting ready to race with a new teammate - Pudsey!
• +1 Daniel Ricciardo: It's not super-original, but I just love the enthusiasm: Thinking bout Austin every second. So eager to get out there and hustle. I want to race!
• +2 Felipe Massa: Having what appears to be a good/emotional final day in Italy, with Ferrari.
• +2 Jules Bianchi: Letting his followers choose the best hashtag for the Austin weekend - #AustinPower or #BianchInUSA?
