Red Bull Racing arrive in Spa Francorchamps for the Belgian Grand Prix this weekend looking for an improvement in fortunes after disappointing outings in Budapest and Valencia.

Points have been hard to come by following Mark Webber's sixth place in the French Grand Prix in Magny Cours in June.

Team principal Christian Horner says: "After a very strong first half of the season, the team has endured a very frustrating past few weeks, with no points scored in the last four races.

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

"The next few circuits, in particular Spa, should play to the strengths of the RB4.

"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."
