Renault's Fernando Alonso insists there can be no mistakes this weekend as he looks to earn another entry in the Formula 1 history books.

Already the youngest driver to win the world title, the Oxford-based 25-year-old is just a point away from joining an elite group who have clinched back-to-back championships.

Michael Schumacher, Ayrton Senna, Alain Prost, Mika Hakkinen, Jack Brabham, Juan Manuel Fangio and Alberto Ascari are the seven to have previously achieved the feat.

Alonso can finish eighth in Sunday's Brazilian Grand Prix and that would be enough to see him crowned world champion again, even if rival Michael Schumacher won the race.

Despite such an advantageous position over Schumacher, who trails by ten points in the standings, Alonso knows no quarter can be given.

He said: "The dream is close to being realised again, but when you have a chance to be a champion there's always pressure.

"Last year I had three opportunities. Here, China and Japan. This year I have just this race, so you cannot lose this opportunity.

"After the last result in Japan, we're in a good position, and now we have to do our best to complete the final part of the job.

"It requires maximum concentration. I'm ready for this last battle and I think the team is ready - no mistakes this weekend."

Alonso's Enstone-based Renault team can also clinch another constructors' title as they lead Ferrari by nine points, requiring just ten for glory.

But all that matters for Alonso, who joins McLaren next year, is winning another drivers' championship, and if Renault take team honours, then so be it.

"The most important thing for me is the drivers' championship - not only for me, for everybody," added Alonso.

"When you see all the publicity on the motorways, everywhere from China onwards, you see only the faces of Michael and myself on the pictures. You don't see the logo of Ferrari and Renault.

"People remember who is champion and the car he drove, but I don't think anyone remembers who was the constructors' champion ten years ago.

"So we try to win the drivers' championship first, and if we can help the team become constructors' champions, it's good for next year, for the money, the position and the brand, but we will see."
