Chelsea are within touching distance of Champions League glory - but standing between the Blues and the final are European Cup masters Real Madrid.
Los Blancos booked their spot in the final four courtesy of a 3-1 aggregate victory over Liverpool in the quarter-finals, while Chelsea survived a late scare against FC Porto to beat the Primeira Liga giants 2-1 over two legs.
Real Madrid and Chelsea have only ever met three times down the years, and the Spanish side have failed to win any of those meetings - losing twice and drawing once to the Blues since 1971.
Chelsea lifted this trophy for the first and only time back in 2012, and look like they could go all the way this year - but they will need to take their chances against a Real team who win semi-finals without breaking a sweat.

Real Madrid vs Chelsea predictions and betting odds
While Real Madrid have enjoyed a spate of clean sheets recently, Chelsea have also recorded three shut-outs in a row before their journey to the Spanish capital.
Advert
The Blues have only conceded a trio of goals during this season's Champions League campaign so far, so expect a cagey affair in the first leg given the quality of both defences.
It wouldn't be a huge surprise if the tie was decided by a single goal over two legs, so the first 90 minutes may be short on chances.
Tuchel also has an FA Cup final to prepare for, but winning the biggest prize of them all in his first half-season at Stamford Bridge would go a long way to ensuring his stay in one of the most unforgiving jobs in the game.
Real Madrid are 13/10 to win, with Chelsea priced at 11/5 to come away with the victory. A draw is priced at 21/10.

Meanwhile, Federico Valverde remains in isolation after testing positive for coronavirus, and Zinedine Zidane could make do without three defenders as Sergio Ramos, Lucas Vazquez and Ferland Mendy keep each other company in the treatment room.
The hosts have been boosted, however, by the recent returns of Dani Carvajal and Raphael Varane and Nacho Fernandez will hope to keep his spot at left-back over Marcelo.
While Eden Hazard and Thibaut Courtois look to influence the game against their former club, Mateo Kovacic will not be reuniting with his former Blancos teammates, as Thomas Tuchel confirmed that a hamstring injury will keep the midfielder out of the first leg.
Chelsea team news and injuries
Aside from Kovacic, Chelsea have no other injury or suspension concerns for the first leg.
Thiago Silva should hope to form a familiar back three with Cesar Azpilicueta and Antonio Rudiger, and Andreas Christensen could drop out as Reece James returns on the right.
Jorginho and N'Golo Kante will continue to man the engine room in Kovacic's absence, but competition for places in Tuchel's front three could hardly be greater.
Mason Mount has established himself as a regular fixture in Tuchel's starting 11, and Timo Werner will not want to be dropped after ended his goal drought.
Elsewhere, Kai Havertz should lead Chelsea's midfield in an attacking role, with Christian Pulisic making way.
