Real Madrid survives
Both teams were going at it early on in the second half with good chances on either side. Chelsea doubled their lead and tied the game on aggregate minute in the 51st minute as Antonio Rudiger headed in a ball past Courtois.
Toni Kroos had a great scoring opportunity off a free-kick but Edouard Mendy made his first big save of the game with a stunning diving save. Chelsea scored its third goal of the game in the 63rd minute as Marcos Alonso with a shot from close beat Courtois wide.
The goal went under review by VAR and upon further review, it was deemed there was a handball on the play and the goal was reversed. Benzema moments later had another big opportunity but his header went off the crossbar and stayed out.
Carlo Ancelotti made his first change of the game in the 74th minute bringing in Camavinga for Kroos. Werner gave Chelsea its third goal a minute later off a weird bounce as the ball rolled into the net and Chelsea now had the 4-3 lead on aggregate.
Ancelotti made two more changes bringing on Marcelo and Rodrygo for Ferland Mendy and Casemiro hoping to add some experience to the backline while bringing in some offense.
The move seemed to work as Real Madrid finally scored when Rodrygo managed to volley a cross from Luka Modric into the back of the net and it was level once again.
Modric tested Mendy minutes later once again but the Chelsea keeper made another diving save to keep the ball out. Lucas Vasquez came in as he was subbed on in the 88th minute for Nacho who replaced Eder Militao who was out due to suspension.
Four minutes were added to the 90 but it wasn't enough as extra time was needed to determine the winner.
Chelsea had another scoring opportunity a couple of minutes later but Courtois once again was able to make a key save. After 15 minutes of extra time, the home side had the lead and was 15 minutes away from a huge win and advancing.
It was back and forth for most of the second part of extra time as both clubs attacked each other hard and it was becoming a very physical game.
Courtois made another game-saving save late in the game as Real Madrid made another change bringing in Dani Ceballos for Vinicius Jr in the 115th minute.
