Nico Rosberg says he is not worried by the fact Lewis Hamilton has previous experience of Formula One title fights.
Mercedes driver Rosberg leads team-mate Hamilton by 22 points with six races remaining as a gripping battle for the 2014 drivers' championship moves towards its conclusion.
An error from Rosberg at last weekend's Italian Grand Prix allowed Hamilton, the 2008 world champion, to claim victory and make up ground on his rival.
Hamilton also came close to winning the title in 2006 and 2010 but Rosberg said: "It's not a concern for me. It might help him, yes, quite possibly having those experiences. But it's not something that I am concerned about.
"I'm focused on my own thing. He is a strong competitor, he has his strengths and weaknesses, but I concentrate on doing my job with my team and getting the most out of it."
While Rosberg was left by disappointed by his mishap at Monza, he insists he is loving every minute of his title chase.
"At the moment, I am enjoying the moment more than I ever have in the sport because I get to a race and I have a car where I know I can be on pole and I can win," he added.
"That's such a special experience and also this confidence that every race we go to, we have this dominant car. That just increases the enjoyment factor even more.
"That's the overwhelming thing at the moment and, thankfully, my mind is just focused on the moment.
"Trying to win [at] Monza was all I was thinking about: getting a good qualifying and a good start and everything. It didn't work out and now I look forward to Singapore.
"I'm going to go out there very optimistic and out there to win, not just to get some points."
