Liverpool arrived at the Tottenham Hotspur Stadium having never lost at Spurs' still relatively-new home. In fact, they were the only Premier League side that not yet tasted defeat at the impressive arena. And as Saturday's match entered the 96th minute, Jurgen Klopp must have thought that his team were about to maintain that record, despite everything that had been thrown at them over the course of the evening.
Down to nine men and having had a goal controversially ruled out for offside - in a decision the PGMOL has since admitted was incorrect - the Reds looked relatively comfortable in defending the 1-1 draw that their backs-to-the-wall performance had deserved. It wasn't the win that would have taken them top of the Premier League following Manchester City's defeat earlier in the day, but a solid point against a fellow unbeaten side with a numerical disadvantage cannot be sniffed at.
And then it happened. Pedro Porro got to the byline down the Spurs right, and his powerful low cross flew into the top corner via Joel Matip's shin on the edge of the six-yard box. The centre-back looked barely consolable when he realised what had happened while Klopp watched on in disbelief as everywhere around him exploded in noise.
Though the result and the suspensions that will have to be served by Curtis Jones and Diogo Jota are damaging for Liverpool, the performance certainly wasn't. As they did at Newcastle earlier in the season, they performed superbly despite being down at least one man, with Cody Gakpo having equalised Son Heung-min's opener late in the first half.
But a first defeat of the season now drops them to fourth in the table below their hosts and Arsenal as they prepare to visit Brighton ahead of the international break. The Amex Stadium has not been a happy hunting ground of late for the Reds, and having lost in such an agonising matter at a place where they have had success before, it will be interesting to see how they lift themselves back up in eight days' time.
