Nico Rosberg says he is much better prepared to beat reigning Formula One world champion Lewis Hamilton to the 2015 title.
Last year, the utterly dominant Mercedes duo fought a close and intense battle for F1's biggest prize, but Rosberg lost out in the end.
"Nico Rosberg has been strengthened by the defeat," the German driver, referring to himself in the third person, wrote on Germany's Sport Bild.
"He is more cunning, because he has learned a lot in the past year.
"Now, there are fewer situations that are unknown to me.
"I'm ready for anything that can happen on the track. I'm better prepared."
Rosberg said one of his weaknesses in 2014 was his wheel-to-wheel duelling against the hard-charging Hamilton.
"Hamilton did a better job (in that area)," he admitted, "so that's what I need to improve for 2015.
"It will be a good year in any case. In the whole of last season I did not make many mistakes. Zero mistakes is always best, but no driver can achieve that - not even Lewis."
