BERLIN, March 14 (Reuters) - Schalke 04 recovered from a goal down to beat lowly MSV Duisburg 2-1 in the Bundesliga on Friday after facing a chorus of boos at halftime.

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 on Friday 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 beating 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."
