Borussia Dortmund have dismissed reports that defender Mats Hummels will leave the club for Manchester City in January.
The defender German champions' chief executive, Aki Watzke, insists that the 24-year-old will continue to play for them, telling reporters that the speculation is "pure nonsense".
Hummels joined Dortmund from Bayern Munich in 2008 and has established himself as a key player for Jurgen Klopp's side.
The Germany international's current contract with the club runs until June 2017.
