Kimi Raikkonen celebrates his 29th birthday on the opening day of the Chinese Grand Prix but admits that, while he would love to take a second win in the event, he may be the one giving presents with team-mate Felipe Massa's title challenge on the line.

The Finn dropped out of contention for back-to-back world championships after finishing 'only' third in last weekend's Japanese Grand Prix, and now has little reason not to back Massa's title bid, but confesses to being in two minds about what he would prefer as the outcome to the penultimate event of the season.

"It is nice to come back here," he said from Shanghai International Circuit, "I have had some good races in the past here and, hopefully, we can have similar achievement this year. Hopefully, I can challenge for a win - the car is definitely improving and it is better for me, although we are still not exactly where we want to be. But this is a different place from the last circuit and, last year, we had a good time.

"I always try to win but, hopefully, we are in a position this weekend to fight for that. However, I know what the team expects from me and I know what they want. They want both championships, so we will see how the race goes and where we are and then maybe there is some different approach we can take. That we will see during the race."

Asked whether he thought it was easier or harder for Massa to overcome Lewis Hamilton's five-point lead in the drivers' championship, Raikkonen admitted that he wasn't going to try and predict the outcome, even though he came from 17 points behind in the final two races of last year.

"It can be easier or it can be more difficult," he reasoned, "It depends really how these last two races go.

"Anything can happen. There are three guys who can win and, last year, I was quite a bit behind and I was still able to do it, so I am not going to start guessing who is going to win. I am sure whoever wins deserves it in the end - and we hope that our team will be there."
