Defending champions Manchester City ran out 2-1 winners over league-leaders Liverpool on Thursday night, but not before a few scary moments.
With the match delicately poised at 0-0, a mix-up at the back lead to Ederson ricocheting a John Stones clearance back towards their own goal-line, only for the Englishman to recover and clear the ball before it crossed the whitewash.
However, in typical football fan fashion, Liverpool supporters have taken to Twitter to express their upset at the decision, after finding an image that displays the ball's shadow clearly past the line.
Here's how Twitter reacted to that contentious decision.
For Man City's official account, the reaction was one of pure relief...
Meanwhile, over in the red half of the media room, there was utter bewilderment.
Despite goal-line technology clearly deeming the ball to have been cleared just short, Liverpool fans have set about finding the perfect angle to demonstrate how far the ball actually went over the line. In a quintessentially English way, some turned to sarcasm to get them through the night's events.
Whilst some just downright overreacted.
Meanwhile, Man City fans and neutrals alike took the opportunity to goad the infuriated Liverpool faithful, claiming that Pep Guardiola's scarf was closer to crossing the line than the ball.
After the game, City staff showed the two culprits the footage of the incident and John Stones' acted like he had it covered all along...
After half a million Liverpool fans signed a petition for Sergio Ramos to receive retribution following his tackle on Mo Salah in the Champions League final, prepare yourselves for the Anfield faithful to demand a rigorous review of the seemingly sound goal-line technology system.
Oh hang on, it actually already exists...
