Button thinks Red Bull ought to start worrying

McLaren driver Jenson Button feels that the Red Bull team ought to be worried about maintaining its lead in the ongoing season, due to a dip in form in the last few races.

McLaren has won three of the last five races with Button winning at Canada and Hungary and teammate Lewis Hamilton claiming top-honours in Germany. In comparison, Sebastian Vettel of Red Bull only managed to win at the European Grand Prix although he has managed to keep his top-spot in the drivers points.

A clear catch up, which may have looked close to impossible a few races back, seems to be round the corner. "It's amazing going into the summer break. As a team we should all be very proud of what we've achieved in the last five races, apart from the reliability issues," he was quoted as saying.

The Briton was pleased with his performance and told Press Association Sport that the Red Bull's are not un-touchable anymore. "The pace has been there, the upgrades have worked, and we've really taken the fight to Red Bull after everyone thought they would be untouchable."
