While holders FC Bayern München and Real Madrid CF are familiar faces in the UEFA Champions League semi-finals, and Chelsea FC are also perennial contenders, Club Atlético de Madrid are breaking new ground.
Bayern and Madrid both reached the last four in 2012/13 while Chelsea were last involved the previous campaign. In contrast, Atlético have never played in the UEFA Champions League semi-finals and last got to the European Cup's last four in 1973/74, when they ousted Celtic FC and went on to lose the only final replay in the competition's history – against Bayern.
Atlético are making their fourth European Cup semi-final appearance overall, whereas neighbours Madrid are in their record 25th and have advanced to this stage for the fourth year running. However, they have not featured in the final since lifting their ninth European Cup in 2002, going out to FC Barcelona (2011), Bayern (2012) and Borussia Dortmund (2013).
There were contrasting evenings for Madrid and Chelsea on Tuesday; the Blues retrieved a two-goal first-leg deficit against Paris Saint-Germain to oust the French champions on away goals, yet Madrid had to survive a stern examination in Dortmund. Leading 3-0 from the game in Spain, Carlo Ancelotti's team trailed 2-0 by the 37th minute in Germany, only to regroup and edge through.
While Chelsea are in the last four for the seventh time in 11 seasons, Bayern – bidding to become the first side to retain the trophy in the UEFA Champions League era – are semi-finalists for the fourth time in five years having disposed of Manchester United FC on Wednesday.
The open draw – meaning no seeding or country protection – throws up the intriguing possibility of an all-Madrid semi-final. The clubs have met in only one European tie, back in 1958/59 when Madrid won 2-1 at home in their semi-final first leg, lost 1-0 away and finally emerged triumphant in the replay, 2-1.
The other teams have plenty of history between them. Chelsea beat Bayern on penalties in Munich to win the 2012 UEFA Champions League final, but lost to them by the same method in the UEFA Super Cup at the start of this term. Bayern overcame Atlético in that 1974 final and have faced Madrid in no fewer than five European Cup semis, winning four, including the most recent, on penalties in 2011/12.
Should Madrid and Atlético be kept apart in the draw, there may be a final between two sides from the same country – which would be the fifth in UEFA Champions League history and second in succession after Bayern's Wembley defeat of Dortmund last May. Madrid were victorious in the first of those, seeing off Valencia CF in the 2000 showpiece in Paris.
A final triumph for Madrid or Atlético would also strengthen Spain's position as the European Cup's most successful nation; the Liga has 13 victories, one more than Italy and England. Should Bayern prevail again, it would be Germany's eighth win, two more than the Netherlands.
The draw will begin at 12.00CET at UEFA headquarters in Nyon, Switzerland, with Luís Figo assisting UEFA General Secretary Gianni Infantino in conducting it.
The semi-finals will be played on 22/23 April and 29/30 April. For administrative purposes, the last step of the draw will define whether the winner of semi-final 1 or the winner of semi-final 2 will be the designated home team for the final. The 2013/14 UEFA Champions League final will be held at Estádio do Sport Lisboa e Benfica, Lisbon, on Saturday 24 May, kicking off at 20.45CET (19.45 local time).
All draw proceedings will be transmitted live on UEFA.com. Our live DrawCentre will also bring you the build-up and post-draw reaction from Nyon.
