We have to improve the situation and we will all have to work very hard Michael Schumacher Race report Race result in full Photos from Magny-Cours

That is the view of Michael Schumacher after Williams scored their second one-two within seven days at the French Grand Prix.

"We need to be concerned about Williams," said Schumacher after being left trailing in third place while Ralf Schumacher and Juan Pablo Montoya staged a private battle for victory at Magny-Cours.

"We know what they do and we must get our act together. Looking at the weekend here, what we achieved was as well as we could have done.

"But we have to improve the situation and we have a big test coming up. We will all have to try very hard.

"What we need to do is keep concentrated to get our act together and improve the situation. Everyone knows what needs to be done but I can't tell you what it is because Ralf is listening.

"I won't divulge secrets. All I can say is that we have a very good car, so do Williams."

We weren't competitive again, so to get third place was a great result Ross Brawn Ferrari technical director Williams 'can win title

In the last two races, while Williams have collected 36 points, Ferrari have scored just 18.

Ralf Schumacher is now 11 points behind his brother in the title chase, with Kimi Raikkonen in second six points adrift of the Ferrari star.

And Williams are just three points behind Ferrari in the constructors' championship.

Michael Schumacher insists, however, that his team will not panic as they seek to get back on terms with Williams with six races to go.

"We have had phases in the past when we were behind and we recovered," he said.

"I am confident we can turn it around and all in all I gained another point in the championship over Kimi."

Ferrari technical director Ross Brawn praised his lead driver's performance.

Schumacher had been struggling for pace compared to the rival Williams and McLaren cars, but he recovered from fifth place to third with a trademark performance around the final pit stops.

The result extended Schumacher's championship lead over McLaren driver Kimi Raikkonen to eight points with six races to go.

Brawn said: "I'm relieved. Michael drove a great race. We weren't competitive again, so to get third place in front of Kimi really was a result for us."

Raikkonen blamed slower cars and a problem with his brakes for losing third place.
