Borussia Dortmund are already working on the contract extension of sporting director Sebastian Kehl, according to the Bild newspaper. Kehl’s current deal runs until next summer. Bild said that club bosses have already held talks with him over an extension, but details of the negotiations are unclear. After a rocky star, Kehl has recently been praised for his work at the club, especially after Dortmund reached the Champions League final last season.
