STOCKHOLM, June 6 (Reuters) - Denmark beat struggling rivals Sweden 1-0 with a first-half goal from Thomas Kahlenberg to move three points clear at the top of World Cup qualifying Group One on Saturday.

Kahlenberg took advantage of a mistake from Sweden defender Mikael Nilsson midway through the first half to fire the ball past goalkeeper Andreas Isaksson.

The win puts the Danes on 16 points from six matches, three ahead of Hungary in second place.

"It was an important step, but we're not there (in South Africa) yet," Denmark coach Morten Olsen told reporters.

"Physically, we're in good shape and that's decisive in a match like this one. All the players are satisfied, it was a fantastic match."

Things are looking less promising for the Swedes, who missed a penalty in the Denmark game and are down in fourth place with six points from five matches.

The group winners qualify for the finals directly while the best eight runners-up from the nine groups go through to a play-off.
