After spending the last two months prising the door open towards a Premier League title challenge, Liverpool kicked it firmly off the hinges at the Emirates.
And now it promises to be quite the sprint finish between two of the greatest teams we have surely ever seen in English football. Game on, indeed.
If it comes down to a straight shootout between Liverpool and Manchester City, then Jurgen Klopp will feel he has the greater weaponry available to him. His substitutions alone were proof of that here against Arsenal as Roberto Firmino added to Diogo Jota's 18th of the season after joining the fray with a certain Mohamed Salah in the second half.
