Ross Brawn has admitted that while it will be tough for Mercedes to challenge the likes of Red Bull Racing and McLaren, he is 'confident' they will get there, eventually.

Mercedes had a dismal weekend in Valencia two weeks ago and for the first time this year, both Michael Schumacher and Nico Rosberg failed to progress to Q3 and the shoot-out for pole.

Race day didn't get much better either, and while Rosberg did claim the final point - moving up to P10 post-race after a number of drivers picked up five-second penalties for speeding under safety car conditions, Schumacher could only finish 15th, his worst result since opting to come out of retirement.

F1 now heads to Silverstone for the British Grand Prix and although Brawn is looking forward to the event and seeing the revisions made to the track, he is under no illusions about the size of the task facing them and the gap to those at the front.

"The British Grand Prix is always a very important and special weekend for our team with Silverstone situated between our factories in Brackley and Brixworth and as one of our home races. We are delighted that the British Grand Prix is secure for the foreseeable future and look forward to experiencing the new track layout at Silverstone this weekend," he said.

"A lot of thought and hard work has gone into the improvement plans and Silverstone will be a venue to be proud of for both the organisers and the thousands of fans who visit over the weekend.

"Our team has had a challenging time over the recent race weekends in Montreal and Valencia but we retain our motivation and are working hard to improve our performance and maximise the potential which can be taken from our latest upgrades. It's a long hard road ahead but we are confident that we will get there."

Despite his 'confidence' though, Ross added that time is running out for them to salvage much from the F1 2010 championship: "We have not done our job well enough. First we have to bring our new aero package up to scratch. [And then] depending on how the results look, we will then decide if we will focus early on next season," he added.
