Pep Guardiola's men let slip a two-goal advantage on Wednesday, as Monaco battled back to win a pulsating tie on away goals.
With the draw to decide the matchups for the quarter-finals coming up on Friday, here is all you need to know about the next round of Europe's top competition.
When is the Champions League quarter-final draw?
The Champions League quarter-final draw will take place on Friday, March 17 at 11:00 GMT at UEFA's headquarters in Nyon, Switzerland. It will be followed by the draw for the same round of the Europa League an hour later.
The quarter-final draw is open and unseeded, so the teams are unranked and clubs from the same country can face each other. Put simply, it is a totally random draw and anyone can face anyone.
The clubs that come out of the hat first for each tie will play the first leg at home.
How can I watch the Champions League quarter-final draw?
The draw can be watched live on UEFA.com, who stream the ceremony for each round on their official website.
