Bayer 04 Leverkusen striker Stefan Kiessling has signed a new deal committing him to the Bundesliga team until 2015. The agreement represents a three-year contract extension for the three-times German international, who leads the Bundesliga scoring charts with 16 goals. "My family and I are very happy in Leverkusen and the club's long-term prospects are exciting," said the former 1. FC Nürnberg forward who joined Leverkusen in 2006. "There's no reason for me to change anything." Leverkusen chairman Wolfgang Holzhäuser added: "We're delighted Stefan will be part of our squad for years to come."
