Pep Guardiola has fired a warning shot at Bayern Munich's tactic-leaking mole, threatening his playing staff with the chop if they are found to be exposing strategies to the German press.
As reported by Marca, the Spanish manager was furious after seeing his line-up and exact style of play appear in Bild before Bayern overcame Borussia Dortmund 3-0 at the Westfalenstadion. Guardiola suggests the damage is irreversible for whoever committed the traitorous act:
"I don't care who the mole is, I want him out," said the former Barcelona boss. "Heads are going to roll. He'll never play for me again."
Bayern CEO Karl-Heinz Rummenigge also waded in on the affair, but opted to take a less irrefutable route of criticism against the guilty party:
"We won't be pulling any NSA business to find the mole, but I'd advise him to stop or there will be trouble," Rummenigge said.
While the actions of Bayern's alleged mole didn't produce any adverse effects during the side's win against Jurgen Klopp's team, continued exposure of tactics could significantly impact Guardiola's quest for glory during his opening season with the German side.
The suggestion that Bayern would use long passes and quick switches of play to topple Dortmund could have seen Klopp alter his game plan for the Bundesliga showdown.
Guardiola is well known for his high-tempo, short-passing game, so it would be some coincidence if Bild merely guessed he would switch to direct tactics against Dortmund.
There has been no suggestion of which player has been divulging key information, but squad disharmony is likely to be one of the only things that can derail another glorious season for Bayern, who look like Europe's dominant side once more this term.
Former Signal Iduna Park favourite Mario Goetze scored the crucial opening goal against Dortmund in a match that saw Arjen Robben add a classy second and Thomas Mueller round the thrashing off at the death.
Guardiola has an almighty task to complete if he is to replicate Jupp Heynckes' treble-winning campaign of last year, even if Bayern remain unbeaten in the Bundesliga and Champions League this season.
While the intense manager's team eventually condemned Dortmund to their third defeat in a row, Bayern's future opponents may be picking up a copy of Bild to get the upper hand when matchday comes around.
