RED BULL BOSS FIRED UP

Red Bull Racing boss Christian Horner has vowed his team will come out fighting this weekend in the wake of a wretched run of form.

Following a strong start to the season, primarily courtesy of Mark Webber, the team has failed to chalk up a point in their last four races.

Red Bull were on course for what would have been a stunning fourth place in the constructors' championship, but have since slipped to sixth.

Somewhat embarrassingly, sister team Toro Rosso have proven a far more reliable outfit of late, with Sebastian Vettel securing a season-high sixth-place finish in the last race in Valencia.

Yet Horner is convinced all is not lost and his team will rise again in the final third of the Formula One campaign.

"After a very strong first half of the season, the team has endured a very frustrating past few weeks," reflected Horner ahead of this weekend's Belgian Grand Prix in Spa.

"It is extremely important we reverse this trend and get back on terms with Renault and close the gap to Toyota.

"Over the past six weeks we have analysed our performance in great detail, and that analysis reveals the chassis is working well, and we have pushed very hard in the factory to improve in all areas.

"Valencia did not play to our strengths, but we are convinced we can bounce back.

"The team has worked well together, putting in concerted effort and man-hours to understand and find solutions to our recent problems.

"So we are going to Spa in fighting mood, determined to come away with some points."

Horner claims Red Bull's main issue has been due to tyres, with other teams making better use of the rubber at their disposal.

Believing the problems have been overcome, Horner is now expecting a far stronger showing in Spa.

"We need to go there and attack the weekend, with both our drivers on top of their game, aiming to finish in the points," insisted Horner.

"At the moment, the section of the grid that includes BMW, Renault, Toyota, ourselves, Williams and now, Sebastian Vettel, is extremely tight.

"As we've seen at the last few races, a tenth of a second can make the difference between four grid positions.

"Even with the long lap at Spa, I think we can expect a very tight grid while the early autumn weather and the race taking place a weekend later than usual can add further unpredictability."
