This weekend in Brazil, the 2007 F1 World Championship will draw to a close. In previous years, the FIA have been accused of manipulating the championship to make it more exciting in the last few races, for example, dishing out penalties to make sure it boils down to a last race finale. This year, there has been no need for any of that stuff, with three absolutely stunning drivers bringing the championship down to the wire. Let's have a look at who they are and why they should win.

Kimi Raikkonen

For: It took Kimi a while to settle into Ferrari, coming from McLaren in 2006. But after a few races wearing the red overalls, you'd think he'd been driving there forever. In a fast and reliable car, Kimi has absolutely shone throughout the entire weekend, practice, qualifying and the race. He has always managed to stay positive, even when the odds are against him, and never given up the championship fight. Whilst the boys at McLaren had to deal with infighting and tantrums, Kimi has kept his head down and got on with it.

Against: Mathematically, it's going to be really difficult for Raikkonen to win the championship. He's 7 points behind two drivers. Although he has had some brilliant drives this year, some weekends he has seemed to be a bit under the weather, and just trying to get through the race. This up-down form may swing against him this weekend.

Fernando Alonso

For: Defending champion Alonso really has the desire to win, if only to prove something to the team he thinks favours someone else. He has the experience of winning under pressure, and he knows how to be a champion and win a championship. The FIA have appointed an official to keep an eye on equality between the McLaren drivers, so this may help Alonso focus on the job at hand.

Against: Alonso has the talent, but his hot-headedness on and off track may affect his performance when it really matters. Alonso really wants to win with a new team, to show that it is he and not the car that is the real star, but the team he chose has not been a good fit.

Lewis Hamilton

For: There's never been a rookie who less deserved the name, Hamilton has been absolutely amazing for the whole season. Considering his lack of experience in Formula 1, there have only been a couple of incidents that are questionable in terms of a future champion. Lewis has won every single class he has entered in the first year, and it's looking mathematically likely that this top class of racing will be no different.

Against: If a sticky situation occurs during the race in Brazil, Hamilton's inexperience may count against him. He will need to be aware of battling too closely with Alonso on track, as the Spaniard has nothing to lose.

That's my round up of the contenders for the race, I'd love to know who you think will be victorious. And check back here for my race review after the event.
