Lewis Hamilton feels he is in title contention - but Mercedes have lot of work ahead

Lewis Hamilton has admitted that as things stand he is in the hunt for the 2013 world title - but stresses Mercedes have a lot of work ahead of them if they're to stay in the fight all through the season.

Hamilton's two podiums at Mercedes already represent more than his predecessor Michael Schumacher achieved in his three seasons at Brackley and come at a time when the Briton's old team, McLaren, are struggling with their MP4-28. With many pundits already had to eat a slice humble pie after questioning the logic behind his Mercedes switch, Hamilton feels his boldness is already being vindicated. "I have a different outlook on this year," he said. "Everyone was saying at the start it was the worst decision I could have possibly made in my life. "But definitely, bit by bit, the more and more we impress and improve they have to stand to be corrected. "Of course, people have an opinion, but I'm just really grateful I'm here and in the fight. "It was such a big change for me, a big step for me. I think I made the right choice."
