Thursday night's clash between Manchester City and Liverpool was a game of margins.
Liverpool came agonisingly close to breaking the deadlock in the 20th minute when Sadio Mane hit the post and John Stones made an incredible goal-line clearance.
From the rebound of Mane's shot, Stones cleared the ball straight into Ederson and watched as it looped over his head back towards goal.
But the Englishman somehow recovered and cleared to safety with Mohamed Salah looking to pounce. Goal-line technology showed the ball was 11mm away from crossing the line.
Sergio Aguero then gave City the lead just before the break with a thumping finish from a tight angle that just about beat Alisson.
Into the second half and Liverpool equalised in the 64th minute when Roberto Firmino headed home Andy Robertson's cross.
Trent Alexander-Arnold's lofted pass to Robertson at the back post was perfectly weighted as it just about avoided Aymeric Laporte's head.
But eight minutes later City were back in front as Raheem Sterling passed to Leroy Sane and the German fired past Alisson, courtesy of the post.
Liverpool can claim they were unlucky at the Etihad, then, because on another day Mane's shot would have gone in off the post and Sane's would have deflected out.
One thing that's certain, though, is Stones' clearance shouldn't have been given as a goal because, as goal-line technology confirmed, the ball didn't cross the line.
But try telling that to one Liverpool fan who has created a petition asking for a review of the accuracy of goal-line technology during the City game.

Pretty embarrassing, right? Goal-line technology has been a godsend in the Premier League and it's wishful thinking to claim a mistake was made during the City-Liverpool game.
Football fans have been reacting to the petition on social media and it's safe to say they think it's hilarious judging by the below selection of tweets.
