Sunday's FA Cup fourth round tie between Liverpool and West Brom was a game that had virtually everything going for it.
The opening twelve minutes alone featured a goal from Roberto Firmino and a lightning fast double from West Brom's Jay Rodriguez to leave the visitors 2-1 up - and yet none of that was the talking point of the first half.
Instead, that would be the use of VAR in two incidents that threatened to shape the entire game.
Craig Dawson, along with everyone else in the ground, thought he had put West Brom two goals clear, only for referee Craig Pawson to consult VAR and rule the goal out for offside.
It was only a few minutes later that Mohamed Salah went to ground in the Baggies' penalty area and began to beg the referee to check VAR again.
Pawson obliged and after an excruciatingly long process, Liverpool were awarded an opportunity to equalise from the penalty spot.
Firmino smashed it against the bar, however, and a goal in first-half stoppage time did eventually give West Brom the 3-1 lead they thought they had earlier.
The second half wouldn't reach the mad standards of the first and was instead primarily about Liverpool's inability to get back into the game, struggling to control the game against the side 19th in the Premier League.
And if any one moment showed their struggles to get any kind of hold on the game, it was Chris Brunt's one-two on 64 minutes - but that's underselling it; the Northern Ireland international pulled off an overhead kick pass while lying on the floor.

And fans loved the effort:
It was far from the finest night of Liverpool's season and leaves Jurgen Klopp's side having suffered defeats to the bottom two teams in the Premier League in their only two games since ending Manchester City's unbeaten run.
Calls for the squad to be strengthened before the end of the month will only get louder now and the game against Huddersfield on Tuesday night suddenly looks like one that could set the tone for the rest of Liverpool's season.
West Brom, on the other hand, have found themselves in the fifth round of the FA Cup - could another Alan Pardew Wembley dance be on the horizon?
