The Bayern Munich coach Pep Guardiola had little time to celebrate his team's 3-0 league win at Borussia Dortmund on Saturday, threatening instead to uncover a mole he said has been leaking team details to the media.
"It does not matter who it is, heads will roll," Guardiola was quoted in the Bild newspaper as having told his players after the game, angry that tactics had made their way into the press before the game. "I will throw him out. He will not play under me again."
The club's chief executive Karl-Heinz Rummenigge confirmed the existence of a mole, saying he should stop or face action from the club.
"We will obviously not bring in the NSA [National Security Agency] to find out who it is," Rummenigge told Sky television. "But I advise him to stop doing it or he will have a serious problem not only with Pep Guardiola, but also the entire club."
Bayern are enjoying a successful first season under Guardiola. They have gone four points clear at the top of the Bundesliga and are already through to the Champions League knockout stage, undefeated so far in all three competitions they are taking part. Saturday's victory was their first against their rivals in the league since 2010 and put them seven points ahead of third-placed Dortmund.
Bayern travel to CSKA Moscow on Wednesday for a Champions League group game.
