Mercedes team boss Ross Brawn has again admitted that the team needs to find more pace from the W01 after Nico Rosberg and Michael Schumacher could only manage eighth and ninth in the German Grand Prix.
Schumacher had started the race in eleventh place but made up places at the start to run in eighth place early on.
The seven-time champion lost places during his stop and slipped behind team-mate Rosberg to eventually take the flag in ninth and he admitted that it was the best result possible in the circumstances.
"I had a pretty good start today but from then onwards, there was not much more that we could do,” he said. “We were targeting to stay out long but we changed the strategy to react to the circumstances and maybe I could have finished slightly higher. But in the end, that would not have changed much in a race where we had hoped to be more competitive.
“What we achieved after my stop was the maximum that was possible. Of course I would have wished for more, especially as our race performance tends to be better than qualifying, but it did not work out. We will certainly not get nervous but we have to sit down, analyse the reasons and put the right solutions in place."
Rosberg admitted it was 'frustrating' to only manage eighth in the race given his podium finish at Silverstone a fortnight earlier and Brawn insisted that the team needed to find more performance to fight towards the front.
"We did a reasonable job today with the car that we currently have,” he said. “It was a little bit frustrating, particularly for Nico, as he was in a very strong position to get past Robert Kubica with his strategy. Unfortunately he lost some time getting tangled up with Mark Webber and ended up coming out just behind Robert.
“The car was more consistent in the race than in qualifying but we have to find some more performance. The team and drivers did a great job, we have good reliability and the two fastest pit stops today, so all the foundations are in place for when we develop a better car."
