BAYERN MUNICH are planning to transform the Allianz Arena for the Champions League semi-final against Real Madrid.
The Bundesliga giants host the Spanish outfit on Tuesday evening in the first leg of the European tie.
The two titans progressed to the final four of the Champions League by both dumping out English teams.
Arsenal were beaten by Bayern while Madrid knocked out Manchester City.
Bayern head into the match against Madrid as underdogs after an inconsistent domestic season which saw them lose the Bundesliga title to Bayer Leverkusen.
The club have called on their fans to help transform the stadium by wearing red-coloured clothing.

Stars Thomas Muller and Konrad Laimer have both added to the call from the club.
They said: "Look in your wardrobes or buy something red - 'Mia san mia' red.
"We players will run out to a red wall at the Allianz Arena on Tuesday."
