Real travel to Munich for the first leg on Tuesday looking to secure their first victory against the Bavarian giants on German soil after eight defeats and one draw in their previous nine matches.

"The past is all about meaningless numbers," Mourinho said. "History will not play a factor tomorrow.

"This will be a different match from the previous ones. This is a semi-final, those who play it want to win.

"Bayern have the special motivation as the final is in Munich, but we have the motivation of being here for the second year in a row. We will see what happens."

Mourinho then seemingly joked about the hostile reception that Madrid expect to receive from the Bayern faithful on Tuesday.

"To tell you the truth, security issues are where UEFA means business," he said. "There will surely be plenty of firefighters if there are fires or hells, as you said.

"Bayern will play with a lot of heart, which is nice in football, but they can also play very well.

"I think that this match will be more tactical than normal and that it will be a great game."

Quizzed on Madrid's chances for the tie, Mourinho said Bayern are highly favoured to go through.

"More important than my opinion is that of those who are more important and more credible than me," Mourinho said.

"Uli Hoeness, Franz Beckenbauer, Karl-Heinz Rummenigge, Oliver Kahn and Ottmar Hitzfeld say that Madrid are not a great side, that Bayern are stronger, and that we have a complex with the 'dark beast'.

"We will be the underdogs in this tie."

The Portuguese coach, who has worked in England, Italy and Spain, also hailed the quality of the Bundesliga but ruled out a coaching job in Germany.

"I cannot work in a country where I need a translator, that is impossible for me," he said.

"Communication is key, talking to the players, setting up the training sessions and I do not speak German.

"It would be very hard for me to coach in Germany. But I really like the Bundesliga, it is an amazing league, and not many coaches would say no to Bayern."
