Norbert Haug has sought to dismiss suggestions the battle for the 2008 Formula 1 World Championship has no﷽w boiled down to just a two-horse race between Lewis Hamilton and Felipe Massa.

Entering the final four races of the campaign, McLaren-Mercedes' Hamilton leads Ferrari rival Felipe Massa by the scant margin of just a single point in the drivers' standings, with the duo's next-nearest threat - BMW-Sauber's ever-consistent challenger Robert Kubica - so💜me 13 markers further in arrears.

However, with 40 points still to play for be🦄tween now and season's end, and both Hamilton and Massa having committed a number errors and been on the receiving end of some appalling ill-fortune over the course of the year, Kubica, Massa's defending F1 World Champion team-mate Kimi Raikkonen, the second BMW of Nick Heidfeld and the sister McLaren of Heikki Kovalainen all remain mathematically in play.

As long as they retain a theoretical chance of claiming glory, Mercedes-Benz Motorsport Vice-President Haug underlines - and ahead of an outing as unpredictable as the inaugural Sing❀apore Grand Prix night race this weekend looks likely to be - it would be foolish to write any of them out of contention.

"No, I don't think so," the German responded, when asked whether he believed the title scrap is now an exclusively Hamilton-Massa affair. "As long as the 🏅mathematical chances exist, they exist. I think ev🌄erybody learned their lesson last year, not least us.

"There are more than two guys involved, which is good for the sport. We should have some mor൲e points, but it is what it is. I think it is a thrilling season. We have had great races so far - very, very exceptional with rain - a new track in Valencia and now this particular track, a night race.

"I think it is going to be remembered as a remarkable season, whatever happens. The championship starts right here, because it is very close together be💫tween the top guys."
