BERLIN (AP):Borussia Dortmund won 2-0 at Freiburg to get its Bundesliga title defence back on track in difficult conditions yesterday.

Heavy snowfall hampered both teams in a hard-fought game.

"In the old days we'd want to go out in weather like this to play football but we weren't allowed because the mothers didn't want to wash the gear. Nowadays we have to go out but we don't want to," Dortmund coach Juergen Klopp said.

Neven Subotic scored in the 54th minute and Mario Goetze made the game safe for Dortmund with seven minutes remaining.

"To win 2-0 here in such conditions is extraordinarily good," said Klopp, whose side beat Real Madrid in the Champions League three days earlier.

Jefferson Farfan's 77th-minute strike was enough for Schalke to complete a perfect week with a 1-0 win at home over Nuremberg. Schalke won the Ruhr derby against Dortmund last weekend and then 2-0 at Arsenal in the Champions League midweek.

"Today falls under the category of dirty hard-work win," said Schalke captain Benedikt Hoewedes. "It wasn't a great game."

obligated to win

Wolfsburg beat Fortuna Dues-seldorf 4-1 away to end its seven-game run without a win in interim coach Lorenz-Guenther Koestner's first game in charge.

"The players were obligated (to win) because the coach was gone," said Koestner, referring to Felix Magath's departure on Thursday. "We scored at the right times and the team never stopped fighting."

Dortmund's first away win of the season leaves them nine points behind Bayern Munich, who play their game in hand against Bayer Leverkusen today.
