Lewis Hamilton has warned his championship rivals that he wants to improve during his bid for a third Formula 1 drivers' crown.
The Briton wrapped his second title as he won the Abu Dhabi Grand Prix at the end of November, finishing 67 points ahead of Mercedes teammate Nico Rosberg in the overall standings.
However, Hamilton said that he is hoping to build on his performances last season, as he aims to join some of F1 greats in becoming a triple world champion.
He told Laureus.com: "At this point in the year I feel very relaxed. I'm always ready to drive. I've been racing since I was eight, so two-thirds of my life.
"I feel good about this year. Well, to be honest, at this point of the year, you don't really know how you feel. I feel fresh. I feel fit.
"I will plan to drive as good as I did last year, but I want to be better. I hope that we have the package and I hope that we have some good races, but I'm just grateful that I get to race again."
If Hamilton were to win the 2015 crown, he would become only the second British three-time world champion after Sir Jackie Stewart.
