You can recap all of the action in our live blog below...
Familiar story
Pep Guardiola has pointed out that once again 'bad decisions' have led to his team collapsing late on in a game.
Countless times this campaign, Man City have given up their lead or conceded goals after defensive errors.
"Many times it has happened this season," Guardiola said to Amazon in regards to slip-ups costing City results.
"I know the the quality of Real Madrid. We took the game in the second half and tried to attack too quick.
"It happens because they [Real] are an exceptional team.
"It happens many times this season. Bad decisions, that's all.
"I take it. It's not about you and me, it's everyone. Yeah, that is all season [injuries]. But we know it."
On next week's second leg, he said: "Of course now it's tough.
"We have to recover. I think now about Newcastle [in the Premier League this weekend] and then go to the Bernabeu."
'We need to look at ourselves'
Man City defender John Stones has revealed what Pep Guardiola has told the team after another damaging loss.
Stones reviewed the game, telling Amazon: "I don't know how to put it into words straight away, it's so raw and frustrating for everyone.
"We were in the game until so late and then it's two situations that happen and we concede.
"It's frustrating as a defender to come away with that result. It's a feeling of anger and frustration."
He added: "We need to see games out better. The manager said we need to take accountability for what we do on the pitch, I think we do that. We need to step up when these bad moments happen.
"Today we had a great opportunity to go to the Bernabeu with a 2-1 lead. It's not done. We have to stay positive, which is difficult now."
"As the manager says we need to look at ourselves and take accountability," Stones continued.
"We were right on top at the start of the game and we know Real have quality to come out in the second half. It is avoidable from us as the eleven on the pitch.
"We have to do better - it's as simple as that.
"We have to keep a positive mentality and try to put it right."
Bellingham reacts
Jude Bellingham has now given his thoughts on Real Madrid's incredible late comeback at the Etihad.
"It was a weird one," he told Amazon. "We played some of our best football of the season and ended up behind.
"I think we were playing well and creating a lot. We were always confident throughout the game that something would drop for us.
"I don't care what form City are in they are still an unbelievable team.
"It's always tricky to play against them and we finally took the chance at the end."
Bellingham continued: "It's always good to take a lead back home and I'm sure the Bernabeu will come through for us.
"It seems like there is up and downs in these knockout games. It's not just game management, it's tactical and it's physiological as well."
Hey Jude, you've made history
It was Jude Bellingham's goal that won it for Real Madrid.
The winning moment was only a tap-in from close range but the goal was a historic one.
Bellingham is now the first English player to score a Champions League goal against an English side for two different clubs.
He's netted against a Premier League opponent for Real after doing so with Borussia Dortmund too.
The 21-year-old superstar always seems to step up in the biggest moments.
Unwanted trend
Manchester City lost a Champions League game in which they led at half-time for the first time since April 2018 (1-2 v Liverpool).
They were unbeaten in 32 such games before tonight (W29 D3).
But maybe we should have expected it considering their recent form in Europe when scoring first.
City have failed to win any of their last four Champions League games in which they’ve scored first, with all those coming during this campaign.
They have crumbled under pressure yet again.

Then Real won two 50/50s to find Jude Bellingham who tapped in from close range to win in dramatic circumstances.
