Schumacher tells Mercedes to stay calm

The seven-time world champion has endured an unspectacular return to Formula 1 this season - with the team failing to find the form it needed to be battling for title glory.

However, Schumacher remains focused on driving Mercedes GP forward and reckons upgrades planned for the Hungaroring can be a big help.

"The German Grand Prix last weekend was clearly disappointing for us but we have seen a variety of performances from our team over the past few races," he said.

"With this in mind, I will still go to Hungary with a positive feeling. It is clear that we need to understand our car better, and the track in Budapest plus more time to evaluate our upgrades should help us in that respect.

"As I said after the last race, we have to remain calm, look into all the details and analyse our performance in order to learn as much as possible from such weekends. That is the way we have to go in order to improve our situation which may already be possible this coming weekend in Hungary."

Team principal Ross Brawn has admitted that the team's car is still not quick enough - but he remains positive for the future.

"The last race weekend in Germany was challenging for us, particularly following the podium finish at Silverstone, and we were disappointed not to be competing further up the field," he explained.

"The team is doing a good job operationally but we need to find more pace from the car and we continue to work very hard to achieve this.

"Hungary is a technically demanding circuit and should be a good proving ground for our latest upgrades, providing further invaluable track testing time, as we work to find the optimum set-up.

"Our two-week factory shutdown just after the race will be a well-deserved rest for our employees and the chance to recharge their batteries before the busy final third of the season."
