SINGAPORE: Lewis Hamilton insists he's not thinking about being crowned Formula One world champion just yet, with four races left and six drivers still mathematically in the hunt. The 23-year-old Briton arrives in Singapore this week with a one-point lead over Felipe Massa - pending the outcome of his appeal hearing into the Belgium Grand Prix - as the championship drives into its decisive, final phase. "I don't think about the title or the other drivers, I just think about doing the best job I can each time I get into the car," the McLaren driver said in sport's official website. "Clearly a number of drivers can still win the title and so I have to make sure that I do my best. "I don't bank on anything other than myself and my team. I am focused on my challenge and my racing." Realistically, the race for the championship is between Hamilton (78 points) and Massa (77), although Robert Kubica (64), Kimi Raikkonen (57), Nick Heidfeld (53), and Heikki Kovalainen (51) are still contenders. Much will depend on whether Hamilton can get his victory at Spa-Francorchamps reinstated after race stewards controversially docked him 25 seconds, demoting him to third. The Briton was found guilty of gaining an advantage by cutting a chicane as he duelled with Ferrari's Kimi Raikkonen in the closing stages of this month's race. The decision, which awarded Massa victory in Belgium, cost Hamilton four world championship points. Should his appeal succeed and he is named the Belgian GP winner with Massa put back to second, then he will extend his advantage to seven points. The points will be a much-needed boost after a poor performance at the last Grand Prix in Italy, where he made an error in his choice of tyres for qualifying which saw him finish way down the grid. He ended up seventh in the race, with Massa sixth. However, Hamilton - who had a sensational rookie season last year, when he finished second in the championship behind Massa's Ferrari team-mate Raikkonen - said he had put it behind him. "Of course it wasn't the result I was looking for going into the weekend, but part of the charm of Formula One is that it is unpredictable," he said. "As I said after the race, I was more relieved than anything to come away with some points. Nevertheless, I really enjoyed the race." Asked if it would affect his preparations for Singapore, the sport's first-ever night race, he replied: "The Monza result doesn't mean anything for the next race. "Each race is different, but I prepare the same for them all. I am looking forward to the (Singapore) race and I'm sure it will be an exciting weekend."
