Mar.11 (GMM/ Nico Rosberg has identified wheel-to-wheel combat as his main weakness alongside reigning world champion and teammate Lewis Hamilton.

With their dominant 2014 Mercedes, the pair duelled intensely for last year’s title but Briton Hamilton ultimately won in the championship finale.

Rosberg did secure F1’s new ‘pole position trophy’ of 2014, but acknowledged that Hamilton was “better” in the all-important area of wheel-to-wheel battling.

Asked by Germany’s Sport Bild if it is true to say Hamilton is a better fighter while Rosberg is a thinker, the German answered: “No, he just did a better job.

“So I need to improve that,” he said. “He was more decisive in the direct duels between us, and that unfortunately had an impact on the final result.”

Rosberg cites Bahrain last year as the perfect example, where their thrilling wheel-to-wheel battle for the lead ultimately went Hamilton’s way.

“This is one area where I need to improve,” he admitted.
