Alonso eyes 'perfection' in Abu Dhabi

With an eight-point lead over Mark Webber and 15 and 24 over Sebastian Vettel and Lewis Hamilton respectively, there are various permutations that would allow Alonso to follow his rivals home and still become champion - but this is not his preference.

"The Interlagos result allows us to be in charge of our own destiny: with a win or a second place we won't need any more calculations," Alonso wrote in his blog for the official Ferrari website.

He said a 'perfect weekend' was required in order to achieve that goal.

"Our approach hasn't changed for this all-important race: we know that if we get everything perfectly right, then we will have the chance to reach the target that we set ourselves at the beginning of the season," Alonso explained.

He did, however, acknowledge that the sheer speed of the Red Bull could be a tough obstacle to overcome.

"We can do it, even if we know our principal opponents are very strong: so far, perhaps apart from one race, theirs has been the best car on every type of circuit. That still doesn't mean we expect to be beaten," said Alonso.

Alonso has had a dramatic season, as after winning the season-opener in Bahrain, he struggled through the first half of the championship before mounting a fightback and coming from 47 points behind to lead the standings after Korea.

The Ferrari driver said that given this turnaround he would regard 2010 as a fantastic season even if Sunday did not go his way.

"We are at the final round of a season that will remain wonderful whatever happens," he said.
