Bayern Munich chairman Karl-Heinz Rummenigge has said that he hopes a mole which has been leaking club information will "fall into hibernation".
A source from the German champions leaked tactical details to the media ahead of their Bundesliga clash with Borussia Dortmund at the weekend.
Rummenigge told ESPN: "I have the faint hope that the mole will fall into hibernation with the first snow, that we can end this really soon.
"I hope that whoever did it will now end it. Anything else would surprise me with this team, which otherwise has a great character."
Manager Pep Guardiola has said that whoever is responsible for the leak will be thrown out of the club.
