Nico Rosberg says he would feel no different about beating Lewis Hamilton to the world championship if it came as a result of the controversial double points finale.

Rosberg fell 24 points behind Hamilton at the United States Grand Prix as his Mercedes team-mate recorded his tenth win of the season. By contrast Rosberg has won four times in 2014 but knows he will have a shot at the title regardless in Abu Dhabi as double points are on offer for the top ten finishers.

That leaves open the possibility Hamilton could lead by more than 25 points going in to Abu Dhabi - the value of one ordinary race victory - but still lose the title if he hits trouble, but Rosberg is nonplussed by that potential outcome.

"It is what it is, I don't really care," Rosberg said. "As long as I have one point more at the chequered flag at Abu Dhabi I don't care why or how. It's the same for everybody ... It's a childhood dream, isn't it, to be F1 world champion? It would be very special."

Though Mercedes is likely to be the team to beat once again in 2015 Rosberg says he is not focusing on the fact he could have a second chance to win the title next year.

"Of course, there's a very, very good chance [of winning in 2015] because our car is awesome and the team is doing an awesome job. I'm not really thinking that far though. I'm just in the moment and want to make the most of it."

Rosberg has only converted two of his nine pole positions to victories this season and, when asked why this was the case after failing to win in Austin, Rosberg replied: "Today it was just driving better that was missing."
