Nico Rosberg says that he has learned to put issues that he cannot control out of his mind as he mounts a late challenge for the 2014 F1 world championship.

The German claimed pole position for the United States Grand Prix at the Circuit of the Americas, but not before brake problems caused headaches for the Mercedes team in final free practice. While Rosberg was not alone in struggling to get the required effect from his retardation - team-mate Lewis Hamilton spun in FP3 and continued to struggle with his brakes in qualifying - he insists that he no longer dwells on that sort of problem.

"We've had a few issues in general on the cars this weekend, on both cars, and we'll try and get them out of the way for tomorrow, but I'm not worried about that at all," Rosberg maintained, "I'm confident we can get the job done and I'm going to concentrate on what I can control, which is my driving.

"It's always frustrating to have something like that, but I've learned to accept it and concentrate on the things that I can influence and just keep on it. That's what I tried to do today and it worked out well."

Out-gunned by Hamilton across all three practice sessions, qualifying did not start to brightly for Rosberg when the Briton again topped Q1, but he subsequently turned the tables to claim both Q2 and, most importantly given the difference in track condition between the two sides of the grid, Q3.

"It was a great day and I'm very happy," he claimed, "It worked out very well and, together with my engineers, I arrived in the end with a car I was really happy with. We seemed to improve the car all the time - we just got it right in the end and that helped me to push.

"I drove the lap really well, but the balance was good. It was quite a challenge because the wind was changing and, this morning, the conditions were quite different, a lot colder. The track was changing all the time and it wasn't that easy to get everything right but, in the end, we got a great set-up, a great car, so I'm pleased with that.

"Of course, first place today is awesome, but the race is what counts, so we need to focus fully on tomorrow and try to bring it home."

Asked how much difference he thought qualifying on the odd-numbered side of the great would make, Rosberg admitted that he hadn't given it much thought, but accepted that it was another thing in his favour.

"It's another extra advantage for starting first," he confirmed, "Of course, the side is going to be important, so we need to make the most of that and stay ahead."
