Mercedes' Lewis Hamilton insisted the World Championship was not on his mind, despite taking the lead for the first time in four months. The Briton moved three points ahead by winning the Singapore Grand Prix after team-mate Nico Rosberg retired. "I'm not really thinking about it. I feel like I'm still hunting, still catching up," he said. This is the third time this season Hamilton has had to close a lead of more than a victory's worth of points. "I'm not sitting here thinking I'm relieved because all year I've had that gap and I've had to be catching it up and then it's gone again. I know what could happen," he added. Hamilton admitted that to have such a large turnaround in one race was "a bonus - those extra points are a huge help". He added: "I just feel relaxed at the moment. I came here to do a job and we managed to get through the weekend without any issues on our side of the garage, which was a real blessing. "I came here thinking 'Nico's going to be quick and consistent; if I can get at least those seven points [the difference between first and second place] and keep chipping away... but getting 25 has changed things a little bit.
