Borussia Dortmund chief executive Hans-Joachim Watzke has warned Chelsea against making an approach for the German club's boss Jurgen Klopp.
It had been suggested that Chelsea owner Roman Abramovich was interested in appointing the 44-year-old at the end of the season, but the Blues have been told that Klopp will not be allowed to leave Germany.
"Chelsea do not bother me one bit, because we have a contract with Jurgen Klopp until the end of 2016, and he will not be going anywhere. It's quite simple. There is no way he will be going to Chelsea," Watzke told reporters.
Dortmund secured the Bundesliga last season, and currently lead the way by five points.
