The Dutch concluded their build-up to the tournament in Austria and Switzerland with a comfortable 2-0 victory over Wales in Rotterdam on Sunday.

The scoreline flattered the visitors as Holland created, and then wasted, numerous opportunities to register a crushing victory.

Even though they were not at their sharpest in front of goal, Van Nistelrooy was impressed with the team's fluency going forward.

He told www.voetbalprimeur.nl: "We must not stop playing with intuition.

"The way we penetrate now, with these players, through the centre of a defence - you rarely see that at the hightest level.

"I can't remember us every creating as many chances with Oranje as we are doing now."

Real Madrid striker Van Nistelrooy is wary of employing such a cavalier approach at the finals though, especially as their group opponents include world champions Italy.

"We will hunt for every ball for the full 90 minutes and the Italians will wait," he said. "When our energy is gone they will hit us hard. We must not allow that."
