Le Guen used to be a French international defender. He had led Lyon to three consecutive French Ligue 1 titles. In 2009, he took over as the coach of Cameroon and steered the team to straight wins in the last four matches of World Cup qualifiers.

Morten Olsen, Denmark's coach since 2000, said: "We did start very well, then we made an error, but we showed commitment and we got back and we won."

"We did get a lot of chances and we could have scored more goals," added he. "We had some elementary mistakes today, but we had a heroic fight and defence."

Denmark will face Japan in their final group match on June 24 when Cameroon will make their last appearance against the Netherlands in the 2010 World Cup which came to the African continent for the first time.
