The Germany legend expects the Primera Division leaders to put up a fight in this week's return after their heavy loss in the first legBayern Munich that Barcelona will not hesitate to use dirty tricks in the return of their Champions League semi-final tie at Camp Nou on Wednesday.
The Catalans were beaten 4-0 at the Allianz Arena last week and the West Germany legend has little doubt that they will give their all in the return in an attempt to turn things around.
"Barcelona will use any trick in the book to throw Bayern off balance. They'll not hesitate to use methods that are against the rules of the game as well as legitimate tricks. They will fight back," Beckenbauer told Bild.
"Barca will not give up. They will give their all to turn things around. They will try to provoke Bayern and use dirty tricks if necessary.
"Barca will probably try to make it a physical battle in order to disrupt Bayern's game. Bayern must try and avoid a lot of personal duels. There will be plenty of minor fouls."
Wednesday's match at Camp Nou is scheduled to kick off at 20:45CET.
