Button says he must be more aggressive in Belgium

Valencia: Brazilian Rubens Barrichello has sent a clear warning to championship-leading Brawn team mate Jenson Button that the Formula One title battle is far from over.

Button recognised that he needed to raise his game in Belgium next weekend after Barrichello won Sunday`s European Grand Prix to move up to second place overall, 18 points behind him with six rounds remaining. "It is better to be consistent and not crash, but if you are consistent and get two points it is not enough," Button, who finished seventh, told reporters. "I am going to go to Spa and be more aggressive, for sure. In every way, not just driving, but with the strategy and with the tyres.”"It is where we have got to be because otherwise it (the lead) is going to be slowly eaten away." Barrichello`s win was the 37-year-old`s first in nearly five years and 100th by a Brazilian. After a difficult start to the season, when Button won six of the first seven races, he is hungry for more. A mistake in qualifying for Sunday`s race left Button fifth on the grid and he then lost out at the start as Red Bull`s title contender Sebastian Vettel moved across aggressively. From then on, he was stuck in traffic. Despite that, Button could consider himself lucky with the Red Bull drivers failing again to take advantage of his difficulties. Bureau Report
