Borussia Dortmund goalkeeper Roman Weidenfeller has signed a three-year contract extension. The 30-year-old's new deal will keep him at the Bundesliga leaders until the summer of 2014.

"Roman has been an important part of our team for a long time," sporting director Michael Zorc told the club's official website.

Weidenfeller has been in impressive form for Dortmund this season, helping them establish a ten-point lead at the top of the table at the halfway stage.

I am happy to be allowed to play a leading part in helping with the positive sporting development at Dortmund.

"I am happy to be allowed to play a leading part in helping with the positive sporting development at Dortmund," he told the club's website. "And I am proud that all those in change at Borussia Dortmund are behind me and have always given me the feeling that they want to continue on the same path as me."

Weidenfeller joined Dortmund from Kaiserslautern in 2002. Despite his impressive performances, Germany coach Joachim Low has all but ruled out his chances of breaking into the national team, saying he is happy with his current goalkeepers Manuel Neuer, Rene Adler and Tim Wiese.
