Bayern great and former chief exec Rummenigge says they must be wary facing Real at the Allianz Arena for the second-leg of their Champions League quarterfinal tomorrow.
"We mustn't make the mistake of getting carried away by euphoria. I'm noticing a certain enthusiasm at the moment and, frankly, I don't like it," Rummenigge told DAZN.
Bayern will be defending a 2-1 aggregate lead and Goretzka insists no-one inside the dressing room are getting carried away.
He said, "We don't need to be warned. We know perfectly well who we're playing against and what kind of match it is."
"We saw in the first leg how quickly Real Madrid can create scoring opportunities. So nobody needs to warn us. We know it on our own."
