Christian Horner: 'Second half of season will be exciting'

Red Bull boss Christian Horner has said that the battle for his drivers to try to usurp Fernando Alonso will make the second half of the season exciting and "full on".

Alonso currently holds a 34-point lead over Mark Webber, with Red Bull teammate Sebastian Vettel another 10 points behind.

"The second half of the year is going to be, again, full on," he told Sky Sports News. "There's going to be a lot of good racing. Fernando's got a 34-point lead but that isn't insurmountable with 25 points for a win.

"It's important we get both our guys regularly beating him - we've got an opportunity hopefully next weekend in Hungary."

Vettel was demoted to fifth place after an off-track overtake on Jenson Button in yesterday's German Grand Prix.
