Hamilton fires warning shot at Button

Former Formula One world champion Lewis Hamilton aims to take the title back from new teammate Jenson Button next season.

Hamilton, who won the world title in 2008, is joined at McLaren in 2010 by current champion Button after his decision to leave the Brawn team with which he won the world crown.

Hamilton said: "You are always working with your team-mate but clearly both of us want to win.

"We will do what we can to work as a team. Otherwise he (Button) wants to keep his world championship and I want to take it back."
