Cameroon's star striker Samuel Eto'o said Monday that the Group E clash against Denmark was a must-win game after the African side slipped to a 1-0 defeat against Japan. A 39th-minute winner from man-of-the-match Keisuke Honda consigned the Indomitable Lions to defeat at the Free State stadium in Bloemfontein with Cameroon unable to conjure an equaliser despite late pressure.

Inter Milan's Eto'o, three times African footballer of the year, playing in a deep-lying role, failed to make a significant impact on the game but insisted that despite the setback the team had played well.

"We've played a good match from the beginning to the end. The Japanese had only one chance and they scored," he said, adding that the young players in the side had performed well. "We had a lot of chances in the second half but not so many in the first but we dominated. Now we have to work. We can't make any more errors and now we have to win against Denmark."

That clash takes place on Saturday in Pretoria, following the meeting between early pacesetters the Netherlands and Japan in Durban.
