With three minutes of the seven added on left to play, Alisson Becker wafted a pass out to the left flank. There was no purple shirt there and the ball drifted out aimlessly for a throw-in.
As a moment it was nothing; as a moment of football it was everything. The home support cheered and jeered it in equal measure, as Liverpool were left to rue how it simply summed up their day of ineptitude.
Arsenal may not want to hear it, but they and their points tally are very much secondary concerns for Sunday’s visitors when it comes to the Premier League title fight. An eventual 3-1 win for the Gunners means the gap is down to two points between the pair. But that number matters less than another: the gap between whoever is top, and Manchester City.
Regardless of which of these teams ends up running the reigning champions closest, or indeed lifting the trophy, the likelihood – nearly the certainty – is that only one of them at most will be finishing ahead of the Cityzens. As such, for Jurgen Klopp and co the ambition isn’t staying ahead of Arsenal, which they still are, it’s staying clear of Pep Guardiola’s team.
