As Chelsea's 3,000-plus travelling fans were making their way back south, wallowing in the unfamiliar sensation of defeat, phones would have lit up and hearts would have been lifted by the news coming in from Manchester.
For at the Etihad Stadium, Sergio Aguero was hobbling from the field in tears. The deadly Argentine striker, who has scored an incredible 19 goals in 20 matches this season, was clearly in agony - you could tell simply from the grimace on his face.
Slowly, the news emerged that every Manchester City fan had feared. Suspected knee ligament damage, MRI scans this week, the possibility of their talisman on the sidelines for weeks, maybe months.
So on the day City trimmed Chelsea's lead at the Premier League summit to just three points, finally breathing new life into the title race, a potential disaster.
As Sky Sports pundit Gary Neville tweeted: 'If Aguero's injury is a bad one then this could be the weekend Chelsea won the league!'
While we won't know for certain about the extent of Aguero's injury until the middle of the week - though he will certainly miss their make-or-break Champions League trip to Roma - we do know that City have been adversely affected before by his absence.
