NYON, Switzerland, Apr 11 (AFP): Titleholders Bayern Munich will face nine-time winners Real Madrid in a dramatic Champions League semi-final, which was drawn Friday.
Surprise packages Atletico Madrid must take on 2012 winners Chelsea in the second semi-final which could create a showdown over goalkeeper Thibaut Courtois who plays for Atletico but is ownned by the English club.
Bayern, who knocked out Manchester United Wednesday, are aiming to become the first club to successfully defend the 22-season old Champions League title.
Pep Guardiola's German champions met Real in the semi-finals in 2011/12. They won that match on penalties in Madrid before losing to Chelsea in the final.
The continental superpowers have met five times in the semi-finals in all, with Bayern winning four.
While Bayern, seeking their sixth European trophy, are trying to reach their fourth final in five years Atletico are aiming to make it to their first.
The La Liga leaders' reward for their stunning victory over Barcelona in the quarter-finals is a match up against Jose Mourinho's Chelsea.
The pair last met in the 2012 Super Cup with Atletico beating Chelsea 4-1.
Mourinho is trying to win the coveted title for a third time with three different clubs after Porto and Inter Milan.
Before the draw, UEFA made a veiled warning to Chelsea that they must not stop Atletico using goalkeeper Courtois.
European football's governing body said any provision in Courtois' loan agreement preventing his participation is against the competition's rules.
"Both the UEFA Champions League and the UEFA Disciplinary Regulations contain clear provisions which strictly forbid any club to exert, or attempt to exert, any influence whatsoever over the players that another club may (or may not) field in a match," European football's governing body said in a statement.
