Michael Schumacher has urged all within Mercedes to remain calm if they are to crack the issues currently blighting the team.

On home soil at Hockenheim, the German Grand Prix weekend was one of the team’s worst this year as they collected their second lowest total of points – just six – from the 11 races to date.

Not for the first time this season, Schumacher and team-mate Nico Rosberg were unable to translate reasonable pace in practice into a strong qualifying performance and solid race day.

Schumacher has now failed to qualify in the top 10 in the three of the last four grands prix, from which he has collected a miserable four points.

As for Rosberg, he could only finish eighth after starting ninth on the grid and has slipped 63 points behind championship leader Lewis Hamilton. With no end in sight to Mercedes’ troubles, seven-times champion Schumacher said: “The German Grand Prix was clearly disappointing for us.

“But we have seen a variety of performances from our team over the past few races, and with this in mind I will still go to Hungary with a positive feeling.

“It is clear 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 was just as disappointed as Schumacher at the team’s lack of performance at Hockenheim, in particular after Rosberg scored a fine third at Silverstone a fortnight previously.

Brawn admits the team are still to discover the optimum set-up.

“The last race was challenging for us, particularly following the podium finish at Silverstone, and we were disappointed not to be competing further up the field,” said Brawn.
