I've run those final minutes of normal time over in my head a dozen times and I don't think there's anything specific to pin the blame on. It just happens sometimes. That's the Champions League, that's football.
As I've seen someone say on Twitter, "Sometimes you 93:20 another team, sometimes another team 93:20s you". As much as humans like to look for patterns in things and like to try and explain the unexplainable, there really is no way to answer all the questions that nights like tonight bring up.
As our old friend Bobby Manc used to say, "This is football". Nights like tonight are why we love football so much, as much as it hurts when you're on the receiving end of its ability to produce unrivalled drama. I just hope the lads can get themselves ready for Sunday, dust themselves down, and get back on with the title race.
But even if we falter from here and end up completely potless, City will still be here tomorrow and we'll still be a joy to watch. Going trophyless is below expectations but it's not a crisis. We went without a trophy in 2013, 2015 and 2017, and if we go without winning anything in 2022 then we'll be fine. We'll just pick it up and start again.
