Motivated Nico Rosberg admits he's yet to peak in Formula 1
Mercedes driver Nico Rosberg says he has not yet reached his peak in Formula 1 and expects to be stronger in 2015 after missing out on last year's title
The German had a tense battle with team-mate Lewis Hamilton throughout 2014, winning five races before ultimately losing out to the Briton at the title-decider in Abu Dhabi.
This year will be Rosberg's sixth with Mercedes and after being a serious title contender for the first time in 2014, the 29-year-old is entering the new season with plenty of confidence.
"I need to find a little bit more and I'm pushing hard to get that," he said. "I'm surely not at my peak of Formula 1 performance yet - I'm only 29.
"I think I have a little bit of room left to improve and come back even stronger, and I'm looking to find that at the moment.
"I'm extremely motivated for this year because I saw glimpses of success last year - and I want to make it happen this year.
"It's my dream to be Formula 1 world champion and it is likely I will have an opportunity to get that this year."
When asked about which areas he has looked to improve on, Rosberg said: "It's just everything. Being an F1 driver is so multi-faceted, it's not just about turning the steering wheel.
"It's about being fit and having your whole life around you sorted, so your focus and energy is on doing the perfect job in the car.
"And it's about working with the team and understanding the technology of the car - there are so many new things this year."
