London, July 8 : Formula One ace Lewis Hamilton has told his title rivals that knocking him off from his top position will take a lot of doing.

Hamilton rocketed to the summit of the world championship for the third time this season after blowing the field away at storm-tossed Silverstone.

He was ,however, too tired to celebrate Sunday's stunning British Grand Prix triumph, and preferred to watch the highlights back at the family home in Tewin, Hertfordshire, and then went to bed.

"I've ticked off Monaco, I've ticked off winning the British Grand Prix. Now, I've got to tick off winning the world championship. Those were the targets for this season. Winning at Silverstone has given me a massive boost and great momentum. I'm in a good spot now but, I have to keep on scoring points," The Sun quoted Hamilton, as saying.

Hamilton believes that he has proved he can deal with the pressure of being Britain's most high-profile sportsman.

"This (race) showed I have the best concentration and I am the strongest," he said.
