Germany hitman Stefan Kiessling has signed a three-year extension to his contract with Bayer Leverkusen that should keep him at BayArena until 2015. "I feel very comfortable with my family and the club has in the long term outstanding prospects so I see no reason to change anything," he said. Kiessling, 25, hit 16 Bundesliga goals for Bayer so far this term as his team trail leaders Bayern Munich by three points. The Bundesliga current top scorer is almost certain to be named in Germany's squad for the 2010 World Cup in South Africa. Watch Kiessling goals
