Jurgen Klopp seemed to think that Mohamed Salah had pulled Liverpool level against Arsenal before belatedly discovering that wasn't the case. However, Liverpool eventually equalised through Roberto Firmino in a thrilling 2-2 draw.
The hosts won a penalty at the start of the second half after Arsenal defender Rob Holding brought down Liverpool forward Diogo Jota trying to clear a loose ball at a corner.
Salah was handed the ball and the responsibility to try and equalise from the penalty spot after his 42nd-minute finish had reduced the deficit, but moments later had his head in his hands.
