With 15 minutes to go at the Etihad Manchester United's position looked perilous. They were 3-1 down and had been chasing shadows in the second half, but then they've pulled themselves out of equally grave positions here previously.
The comeback from 2-0 down at half-time to deny City a derby-day title success in April 2018 came from an equally improbable position, when Pep Guardiola's side were so dominant in the first 45 minutes they only question looked to be how many they would score.
Instead, United rallied that day and found a response that was as baffling as it was brilliant. So while there looked to be little hope with 15 minutes to go yesterday, there is never no hope in that situation.
