Hamilton plays down talk that title is won

Championship leader Lewis Hamilton has played down the suggestion that he has "one hand on the trophy" - with the Mercedes man being 40 points ahead of next-closest Sebastian Vettel.

Hamilton already has four world championships to his name and he is 40 points clear in a bid for his fifth.

With the comprehensive lead in the drivers' standings and his team Mercedes comfortable in the constructors' championship - he is refusing to get carried away and knows there is still loads of hard work to put in.

"I don't think you ever have one hand on it - you either have both hands on it or you don't," Hamilton explained. "There is still a long way to go. A lot of points available. Six races is still a lot of races. The job, the target and the approach is still exactly the same."

Hamilton believes he is "stronger than ever" at the moment but also heaped the praise on his championship rival Vettel, for the challenge he is putting up.

"I feel healthy, happier and stronger than ever," Hamilton added. "It still feels like it has been a long year. It has been the most challenging year fighting against another four-time world champion. The stakes are as high as they have ever been.
