BERLIN (AFP) - Borussia Dortmund announced Wednesday that Juergen Klopp will quit as head coach at the end of the season after seven years in charge and two German league titles.

The 47-year-old had a contract until 2018, but asked to be released early after a poor series of league results left Dortmund bottom of the table in February before climbing to their current position of 10th.

Klopp was the first coach in Borussia's history to win the german double of domestic league and cup titles. He steered Dortmund to the 2013 Champions League final, when they lost at Wembley to Bundesliga rivals Bayern Munich, having won the 2011 and 2012 German league titles.
