Schalke beat Duisburg

Germany defender Heiko Westermann got the winner in the 74th minute, firing home from the right with an acrobatic strike after Gerard Asamoah's header came back off the bar.

Germany striker Kevin Kuranyi equalised for Schalke on the hour after getting his knee on a low cross from Ivan Rakitic.

Duisburg had taken the lead against the Champions League quarter-finalists -- who were drawn against Barcelona - in the 21st minute to stun a sell-out crowd of 61,482.

Bulgaria striker Blagoy Georgiev intercepted the ball in midfield and made a superb solo run down the left before bting goalkeeper Manuel Neuer with a fine shot inside the far post.

"We had a hard time finding the openings," said Schalke coach Mirko Slomka after Duisburg played with 10 men behind the ball for much of the game.

"And after we fell behind our fans weren't amused. But in the second half we threw everything we had at them and were able to turn it around."

Duisburg coach Rudi Bommer blamed second-half mistakes.

"We played very well defensively in the first half and had some good scoring chances as well," he said.

"But in the second half we didn't have the courage we had in the first half."

Schalke stay fifth with 41 points, nine behind leaders Bayern Munich who visit bottom club Energie Cottbus on Saturday.

Duisburg are a point above Cottbus in 17th place with 18 points.
