Van Nistelrooy warns Dutch against complacency before Czech clash

The Netherlands' assistant coach Ruud van Nistelrooy said the team cannot afford to take its foot off the accelerator in the European Championship after topping Group C, and must learn from mistakes made in major tournaments in the past.

The Dutch began their campaign with a 3-2 victory over Ukraine, going on to win all three group matches to set up a last-16 clash on Sunday with Czech Republic. The Czechs qualified after finishing third in Group D with four points. Former Manchester United and Real Madrid striker van Nistelrooy was part of the Netherlands side that was knocked out of the 2006 World Cup in the last 16 by Portugal and suffered a similar fate in Euro 2008, when the Dutch lost to Russia in the first knockout round.
