Williams secured its first double points score of the F1 season at Silverstone although technical director Sam Michael admits that the team's performance through the first half of the season hasn't been up to scratch.

On the back of his fourth place finish in Valencia, Rubens Barrichello picked up a solid fifth place in the British Grand Prix while team-mate Nico Hulkenberg took the flag in tenth place - scoring his first point since the Malaysian Grand Prix back in April.

While Michael was understandably pleased with both drivers picking up points, he did admit that the first half of the year as a whole had been disappointing and said there was plenty of room for improvement.

"Both drivers in the points today is another good result for the team," he said. "Rubens had a great first lap and embedded himself into a points-paying position. Nico did an excellent job in his first stint, following a different strategy and staying out on his set of options for as long as possible. All of the aero upgrades worked well on both cars, which shows the factory is making good progress. We now need to maintain that progress.

"We aren't happy with our first half performance, it hasn't been good enough. We're playing development catch-up with the whole car package. That work does seem to be paying off now, but there's still a lot more work to do."

Barrichello himself agreed that the team isn't currently where it should be in the pecking order but said he was pleased with the progress being made.

"It was a good race today," he said. "It started well on the opening lap and I managed to claim some positions without too much trouble. Around the stops and the Safety Car, we gained a position from Alonso and lost one to Jenson, but overall we were in a safe position to come home in fifth. It is a great effort from the team to achieve a top five finish two races in a row - not so much in absolute results, but the direction of improvement.

"The team is still not quite where it belongs, but we are quite happy with our performance today. We will continue to think and work positively and continue our forward progress."
