'Guardiola must change his attitude'

Bayern Munich coach Pep Guardiola has been warned about his future conduct by head of the German Football Association's referee commission Herbert Fandel following his behaviour during the 1-1 draw with Schalke last week.

The ex-Barcelona trainer raced to confront the assistant referee during the 1-1 draw with Schalke earlier this month after Robert Lewandowski saw a goal disallowed, only to raise eyebrows again minutes later when he embraced the fourth official back in his technical area after Arjen Robben netted the opening goal for Bayern.

Although Guardiola dismissed the incidents after the game, Fandel has now hit out at the Catalan and warned him to not repeat the act.

"Pep Guardiola would do well to adjust his attitude," Fandel told Sport Bild.

"With all due respect to strong emotional reactions, we crossed a line. A coach leaving his technical area to rush towards an assistant at the corner flag needs to be sent to the stands.

"The fact that he got away with a warning against Schalke should remain an isolated case.

"You cannot touch the body of a referee. Pep Guardiola should change his behaviour immediately."
