Czech striker Jan Koller will leave Borussia Dortmund at the end of the season after rejecting an offer to extend his contract with the German club.
"I want one more good season with the fans and to sign off on a successful note in Dortmund," the giant Czech forward said.
Dortmund said the 32-year-old would seek a new challenge abroad after his contract expired at the end of June 2006. Koller, 2.02 metres (6 feet 8 inches) tall, moved to the 1997 European champions from Anderlecht in 2001 and helped steer the club to the German championship in 2002.
