Reigning world champion Lewis Hamilton has admitted that the “increasingly intense” battle to retain his title means there is scope for more mistakes in upcoming races.
Hamilton, who holds a 28-point lead over Mercedes teammate Nico Rosberg after his sixth win of the season in Belgium, suffered a scruffy race in the previous Grand Prix at the Hungaroring.
Writing in his column for the BBC Sport website, Hamilton said: “The season has gone well so far but there are a lot of challenges coming up.
“As the year comes to a climax, it becomes increasingly intense. It's easy to tighten up, and when you do that you are prone to more mistakes.
“It is going to be busy, there is a lot of travelling and there will be sacrifices to be made – I will have to weigh it all up because this is the most important part of the season.”
Speaking about his new blond hairstyle this weekend, which he had dyed in Los Angeles, Hamilton wrote: “I was at the hairdresser and I just thought: ‘I'm going to try it, let's do it.’ Zero cares.
“It's short term. I'll keep it for this weekend and then I'll probably go back next week, and who knows, maybe I'll do something different.”
