Sebastian Vettel has every confidence Red Bull Racing will be on the ball in Belgium this weekend.

Vettel has had the opportunity to restore his spirits during the recent summer holiday after missing out on another victory from pole position in Hungary just over three weeks ago.

The 23-year-old has now failed to convert pole into a race win six out of seven times this season, which has without doubt cost him the lead in the championship.

Remarkably, of the five contenders in line for this year's crown, Vettel is the only driver yet to lead the way in the title race.

However, he remains only 10 points adrift of team-mate Mark Webber going into the final seven grands prix of the season, starting out at Spa on Sunday.

Although the track is not expected to favour Red Bull as others have done recently, Vettel firmly believes he will again be in contention for honours.

"I love Spa," exclaimed Vettel.

"It has some of the best corner sections in Formula One. They're long, fast-flowing and suit our car.

"Our weakness will be the long straights and, with uphill sections too, we know it won't be easy for us, but I am optimistic for the race."

Despite the recent break, Vettel refused to let his standards slip and, instead of spending time chilling out on a beach, opted to stay in shape in preparation for the tense battle ahead.

"The long break allows you to do more scheduled training, as when there are races every other week it's difficult to improve your level of fitness," added Vettel.

"I tried to switch off for the first part of the holiday, and then did some more intensive training in the second half in order to be well prepared for the reminder of the season."
