Fernando Alonso insists that he isn't even thinking about a second world championship trophy sitting in his office, despite leaving Suzuka needing just a single point from the final round to clinch the 2006 title.

The Spaniard's surprise win in the Japanese Grand Prix, coupled with the Michael Schumacher retirement that permitted it, has left him ten points clear at the top of the standings, but Alonso was playing down suggestions that he already has one hand on the trophy, despite the odds being stacked overwhelmingly in his favour. The Renault man needs to finish eighth or better in the Brazilian Grand Prix next weekend, even if Schumacher were to win the race, while his rival has to take maximum points and hope that the Spaniard fails to score.

"I think it's a little bit too early to realise what happened today - which was a complete surprise for us - and, for sure, the same thing can happen in Brazil and you lose everything," Alonso said immediately after the Japanese race.

"I think we thought the championship would be decided in Brazil but, for sure, we now have a much better position than before because, when we were on equal points, we needed to beat Michael, we needed to beat Ferrari, and it is not easy to approach the weekend with that pressure.

"Now we only need a few points, and this becomes a little bit easier. But you need to finish the race and this is sometimes unfortunately not the case - for mechanical problems, for bad luck, for an accident, for a spin and putting the tyres in the gravel. You never know what is going to happen in the race. We need to go there with maximum concentration, maximum professionalism and try to do it."

Alonso's individual task is clouded slightly by the ongoing battle in the constructors' championship, where Renault's 1-3 finish in Japan - sandwiching the remaining Ferrari of Felipe Massa - leaves the Spaniard and team-mate Giancarlo Fisichella with a little more work to do. The regie heads to the last round nine points to the good but a Ferrari 1-2 in Brazil would leave Alonso and Fisichella to claim third and fourth to ensure the title heads to Enstone and Viry-Chatillon rather than Maranello. Anything lower leaves Renault open to losing its advantage or tying on points, both of which would see the initiative swing towards Ferrari,

"We must try to be concentrated and not make any mistakes in terms driving," the Spaniard said, "For sure, the team knows what to do but, if I can say something to them, it will be to be so conservative. It is no time to risk in Brazil. For me, I hope everything goes well."

However the Renault team approaches the final round, Alonso knows that the race will seem very drawn out.

"I had a very long race in Brazil last year," he reflected, remembering his title-winning event, "All the race, 70 laps, in Brazil, it feels very long. But you find motivations every lap. Sometimes you have to fight for a position. Sometimes, it's approaching the pit-stop, or after the pit-stop, people you are lapping... There are no moments to be bored or to lose concentration or for the race to become too long. You are always motivated by something..."
