Jurgen Klopp extends Borussia Dortmund contract to end speculation about his future Borussia Dortmund's highly-rated manager Jurgen Klopp has ended any speculation about his future by extending his contract with the club until 2018. The Dortmund boss has been linked with a host of top jobs in recent years and only three days ago it was rumoured that Germany were lining him up to replace current national team boss Joachim Low. However the 46-year-old has reaffirmed his loyalty to the club where he has had great success, extending his current contract - which runs to 2016 - by a further two years. "No one needs to call until 2018," a smiling Klopp told reporters during a news conference in Dortmund. We feel a lot of extraordinary trust and confidence in this club. This is a clear sign. It is an honour that some international top clubs consider that we are doing good work here but I do not belong to those who constantly think about whether the grass is greener somewhere else. So thank you but no chance. "To have four and a half years of secure employment in our business is unusual but we will not go soft," Klopp added. Instead we have a huge appetite to take on the tasks at hand. We want to continue the successful path and ideally make it even more successful. Having come agonisingly close to the Champions League trophy last season, only to be beaten by German rivals Bayern Munich, Koll is already building for the future, rather than preparing himself for a new challenge elsewhere. "We want to have the tranquility to plan the future of this wonderful club together," said the 46-year-old. Together we have written an exciting story here, maybe the most exciting and thrilling football story of the past few years. But I do not have the feeling that I have to start with any final chapter yet. Klopp has been praised for his recent success with Dortmund Klopp's assistant Zeljko Buvac also extended his own deal by two years. "Since you should never separate that which belongs together, we've extended the contract of our head coach and his team once again," said the club's general manager Hans-Joachim Watzke. Klopp added: "We're all still just a little bit in love with this club and the way in which things are progressing here." Since he took charge of the club in 2008, Klopp has won two Bundesliga titles, the German domestic cup and last year was runner up in the Champions League as rivals Bayern Munich pipped them to both domestic and continental success. This season his side sit one point behind Pep Guardiola's team having played their first ten games of the season
