Chelsea will learn their Champions League semi-final fate when the draw takes place in Nyon on Friday afternoon.
The Blues enter the final four after knocking out Paris Saint-Germain on away goals, having lost the first leg at Parc des Princes 3-1 before securing a dramatic 2-0 win at Stamford Bridge.
The draw, scheduled to start at 12:00 CET, will be conducted by Uefa general secretary Gianni Infantino and director of competitions Giorgio Marchetti, and will be assisted by the ambassador for the final in Lisbon, Luis Figo.
WHEN ARE THE CHAMPIONS LEAGUE SEMI-FINALS?
The semi-final ties involving the four winners from the Champions League quarter-finals will be determined by an open draw. At this stage of the competition, no teams are seeded and clubs from the same national association may be drawn against each other.
The semi-finals are played on a home-and-away basis, with the first legs on Tuesday 22 and Wednesday 23 April and the return legs the following week, Tuesday 29 and Wednesday 30 April.
WHICH TEAMS HAVE QUALIFIED?
Both Madrid sides are joined by the Bundesliga champions - and titleholders - and one remaining Premier League representative.
The fact that the semi-final ties will be determined by an open draw means that Atletico could be paired with city-rivals Real again, while a rematch of the 2012 final between Bayern Munich and Chelsea is an option, too.
PLAYERS TO WATCH
Although the Champions League was robbed of stars such as Wayne Rooney, Robin van Persie, Lionel Messi, Neymar, Zlatan Ibrahimovic, Edinson Cavani, Robert Lewandowski and Marco Reus, there will still be plenty of stellar names in the last four.
Two out of the three players who made up the podium of the 2014 Fifa Ballon d'Or - Cristiano Ronaldo (Real Madrid) and Franck Ribery (Bayern Munich) - will be present.
Additionally, Real Madrid boast stars such as Gareth Bale and Karim Benzema in their squad, Chelsea have Eden Hazard, Oscar and Samuel Eto'o among others, while Atletico can call on Diego Costa, David Villa and Thibaut Courtois.
Not convinced just yet? How about Arjen Robben and Mario Gotze (Bayern), Koke (Atletico Madrid), Frank Lampard (Chelsea) and Luka Modric and Angel Di Maria (Real Madrid)? The list goes on and on!
