The Dutch have taken the tournament by storm in smashing a total of seven goals past 2006 World Cup finalists Italy and France to secure top spot in Group C and cruise into the quarter-finals.

Along with Spain and Portugal, they are now favourites to lift the title, with their vast array of forwards in sublime form and their often suspect defence holding up in their opening two matches.

But skipper Van der Sar, a veteran of more than 120 caps for his country, is preaching caution ahead of the knockout stages.

"We are only in the quarter-finals," the Manchester United goalkeeper, 37, warned.

"I have been going around for a long time and to be in the quarter-finals is nice, but it doesn't bring you any silverware.

"It's a great start for us - nobody expected us to come out and beat the world champions and then France.

"We will enjoy it but we still have to focus on our next game. And then we still have maybe three more games to play."

Holland produced a lesson in counter-attacking football to blow away France in Bern on Friday, the same way they destroyed Italy four days earlier in the same city.

Les Bleus have not conceded four goals in a match since 1982, and their defence has been one of the strongest in world football over the past few years.

But it could not cope with the brio and pace of the Dutch attacks, especially in the second half of the 4-1 victory at the Stade de Suisse Wankdorf.

Dirk Kuyt had opened the scoring with a simple header from a corner in the eighth minute, but it was after the break that the Oranje really put on a show as France pushed forward and left gaps at the back.

Second-half substitutes Arjen Robben and Robin van Persie exposed the French by finishing off flowing team moves in some style, before Wesley Sneijder added gloss in injury time with a trademark strike from long range.

"Holland must have had five or six chances, and scored four goals," said France right-back Willy Sagnol, who set up Thierry Henry for Les Bleus' only riposte.

"We had 10 of them (chances) and it finished 4-1 - it doesn't reflect the match.

"But if they continue like that, they will go far."

It could all have been so different had Henry, returning from a thigh injury, made the most of a host of opportunities that came his way at the start of the second half.

The first saw his goalbound effort strike the hand of Andre Ooijer, but French penalty appeals were waved away by German referee Herbert Fandel.

Henry was then set free by Florent Malouda's spectacular overhead kick but, one on one with Van der Sar, the Barcelona star lofted his lob clear of the bar.

The former Arsenal skipper's glancing finish in the 71st minute made it 2-1 but Robben's glorious strike just seconds later restored Holland's two-goal cushion and the game was up for the French.

"We have a good all-round team," said Holland coach Marco van Basten.

"We have an excellent goalkeeper, strong defenders, intelligent players in midfield and an excellent attack.

"The team spirit is really, really good. We played excellently against Italy and to offer a performance against France four days later is a feat.

"This indicates there is a great team spirit."

France now need to beat Italy in their final game to stand a chance of finishing second in the group.

But even a victory over their old rivals in Zurich on Tuesday would be made redundant if Romania, who are a point ahead of Les Bleus, defeat what will surely be a second-string Dutch team on the same night.

"When everything is going well, life is beautiful and everyone is happy," said philosophical France coach Raymond Domenech.

"When you lose, life is not so beautiful. In high-level football, you have to keep on hoping.

"The team is still here, there is another match left."

After four years in charge, Domenech could face the boot if France fail to qualify for the knockout stages but he is putting those concerns to one side for the moment.

"My big worry is the next match against Italy," he added.

"That is more important than the future of the staff and the manager."
