Formula One driver Button optimistic

Former world champion Jenson Button said on Thursday that he was approaching his landmark 200th Formula One race this weekend in an optimistic frame of mind, but expecting a tough fight between the three top teams. The 2009 champion, who claimed the first of his 10 F1 wins in the Hungarian race of 2006 after 113 starts, added that he did not expect any favours from his rivals as the championship settles into a closely-fought battle. "If you look at the last few races we've all been making improvements in different areas," said the McLaren driver. "There's been a good fight and no easy victories. "There is going to be a lot of competition. We are all pushing as hard as we can and I don't expect any favours from anyone. "I think that it's a great time for Formula One now to have three top teams fighting at the front. Nobody knows who is going to come out on top." The 31-year-old Briton is one of the drivers to have enjoyed a victory during a recent streak of races that has seen four different victors at four different Grands Prix. He was triumphant in a rain-hit race in Canada last month - just as he was in the rain in Hungary five years ago. That win was followed by victories for defending champion Sebastian Vettel of Red Bull at the European Grand Prix, two-times champion Fernando Alonso of Ferrari in Britain and Lewis Hamilton, his McLaren team-mate in Germany last Sunday. "Hopefully, it will be very close again and it will be a great race - and I can finish this time," joked Button, who had to retire with hydraulics problems at the Nurburgring last Sunday. Thanks to his supremacy in the opening races, Vettel has a lead of 77 points ahead of Webber in the title race with Hamilton third and 82 points further back. Webber is the only one of the top five who has yet to win this year - and he plans to end that run on Sunday. "I'm looking to give it another crack this weekend," said Webber, whose strong record in Hungary includes a race victory last season. "The layout of the Hungaroring track should be suited to our car," he said. "And it is important we have a good race because the next two tracks, Spa-Francorchamps and Monza, after the summer break, are traditionally places we do not go so well. "I guess I've been consistent, but I'm not getting carried away with my recent run of results - we still need to tick that final box. I need a win. "But, you know, McLaren and Ferrari aren't hanging around and qualifying has tightened up a bit. Whether it's three teams fighting remains to be seen but two could definitely challenge for the victory."
