Beating Nico Rosberg to F1 drivers' championship is 'pretty impossible': Lewis Hamilton

Defending champion Lewis Hamilton may face "impossible odds" but has vowed to "give everything" to stop fellow teammate Nico Rosberg from winning the Formula One drivers' world championship at the season-ending Abu Dhabi Grand Prix on Sunday.

Hamilton has come within striking distance of Rosberg in the drivers standings after winning the last three races of the season.

Meanwhile Rosberg only needs a top three finish this weekend to clinch his maiden title and stop Hamilton from becoming the first British driver to be crowned a four-time Formula One world champion.

Hamilton, who drove superbly in the wet to finish firstat the Brazilian Grand Prix, was in no doubt of the scale ofthe task he faced, telling the formula1.com website: "It's notbeen a perfect season and I'm faced with pretty impossibleodds no matter what I do this weekend.

"I can't and won't give up. You never know what might happen -- however unlikely it may seem," added Hamilton,plagued by reliability issued earlier this season.

"I'll be proud of myself and what I've achieved as longas I feel I've given my all and performed at my best. Whateverhappens, I'm proud of everyone who's been a part of thesuccess we've shared over the past few years.

"I'm approaching this weekend the same as I do everyrace. I want to win and I'll give it everything to finish theseason on a high."

Meanwhile Rosberg, bidding to emulate his father Keke,the 1982 world champion, said: "In Brazil, after the race, Iwas joking that I would still be taking things one race at atime, but the more I think about it, the more that's actuallynot as crazy as it sounds. I have to treat this like any otherrace."     

The German added: "Nothing in this sport is easy, so thiswon't be any different and I still have to go all out for agood result.     "I have great memories from winning at this track lastyear and it's somewhere I've usually been strong in the past,so I have every reason to feel confident."
