Alonso unconcerned by dirty tricks.

Fernando Alonso has played down suggestions that he could be the victim of a dirty tricks campaign in order to ruin his chance of taking a second successive world title at Interlagos this weekend.

Despite holding a ten-point advantage over Michael Schumacher going in to the final round, the Spaniard knows it is essential that he score at least one point to take the crown even if his German adversary wins the race, but refuses to believe that anything sinister may be cooked up to disrupt his weekend.

"I have no worries at all," he stressed, "I think all the drivers in the last race want to do a good result because the motivation is not the same as for the first race. It is the last race and everyone wants to do a good result to prepare [for] the winter and so on. I think it will be a completely normal race."

Admitting that he would put his own title ambitions ahead of those of the Renault team, Alonso also insisted that he would be doing everything he could to secure the points necessary for the team to clinch both titles.

"To be honest, for me, the important thing is the drivers' championship, not only for me, for everybody," he told journalists during Thursday's press conference at Interlagos "We see all the publicity on the motorways, everywhere from China onwards, and I think we only see Michael's and [my] face on the pictures. You don't see the logo of Ferrari and Renault. I think the people remember which driver is the champion and which car he drove. I don't think anyone remembers, ten years ago, who was the constructors' champion.

"For sure, it's an important championship, but I think the team and myself know which one is more important and we'll try to win this drivers' championship first. Of course, if we can help the team to become constructors' champions, it's good for next year - for the money, for the position and for the brand - but we will see."

Despite his comfortable lead, the Spaniard admitted to feeling the pressure to succeed, but this time without the safety net of two further races.

"Always, when you have the chance to become champion, you always have the pressure," he said, "The motivation and the dream is close to being realised again. Last year, for sure, I had three opportunities - here, China and Japan - but, this year, it's only the last race and, for sure, you cannot lose this opportunity as I was able to lose the opportunity last year. So it's maximum concentration.

"It's completely different to last year. I think, this year, [we had] the same advantage in the first part of the season - around 20 to 25 points - and we kept it last year a little bit thanks to the mechanical problems that McLaren had. When normal races happened, the McLaren was quicker than us and it was impossible to fight with them - sometimes, they had problems and we got the advantage back again. This year, with Ferrari, sometimes we can fight with them and we can win and we can lose but, for sure, I had a much better feeling last year about the championship, the sport and about everything.

"However, I think the team is ready for this last battle. I am ready as well and we arrive in a good position thanks to the Japanese result . We will just try to do our best and do the final part of the job."
