2009 F1 World champion Jenson Button has said that the sport is now a lot more challenging than it was 10-15 years ago.
Button, who of course won the title in Brazil on Sunday, has already stated that his goal now is to defend his crown and break the mould by doing something no British driver at the highest level has ever accomplished before - claiming back-to-back title glories by winning again in 2010.
Speaking to Scottish newspaper The Daily Record
though, the Englishman was keen to emphasise that won't be easy, especially given the field is so evenly spread, with so little between those at the top and those nearer the rear.
"It's getting more and more difficult. It's a very competitive sport. I'm sure it was in the 70s and 80s but now, for me, every single driver on the grid deserves to be there," he told the 'paper.
"They are very talented. They're not paying their way into the sport. So to have the competitiveness between the drivers but also the teams - it's amazing how close it's been this season.
"One second has covered the front to the back of the grid whereas 10, 15 years ago that was first to third on the grid.
"It's a lot closer and has made it a lot more difficult for everyone. It's going to be tough but the title is every driver's aim and it will be my aim next season too."
Button meanwhile, who spent less than half an hour partying after his success in Interlagos, noted that he just wants to let it sink in now.
"It's a great feeling and I'm planning on enjoying it for a few more days," he added in a separate report in The Mirror
in the countdown to next weekend's F1 finale in Abu Dhabi.
"I'm not going to forget about it for a very, very long time. Every morning I wake up until the first race next year I will have a big smile on my face."
