BERLIN, Nov. 25 (Xinhua) -- Bayern Munich coach Pep Guardiola was angered for one of his players leaked team tactics to press before their clash against rivals Borussia Dortmund, Bild reported on Monday.

The German giants coach has threatened to "to do everything to find out" who had leaked information and kick out the player from his playing squad, according to Germany's Bild report.

Club chairman Karl-Heinz Rummenigge gave his backing to the coach when asked on Sky television Sunday evening about the alleged mole.

"I can only advise whoever it was to quickly put a stop to it otherwise he will have a serious problem, not only with Pep Guardiola but with the whole club," Rummenigge said.

The alleged leak of tactics has done no harm to Bayern's title defense as the reigning champions beat Dortmund 3-0, extending 38 games without defeat.

Bayern are four points clear of Bayer Leverkusen and seven ahead of Dortmund at the top of Bundesliga.
