The disastrous VAR offside decision that has left Liverpool demanding a Premier League match is replayed was made inside a new state-of-the-art facility.
The bespoke VAR Hub at Stockley Park in west London, where video officials watch the action on banks of television and computer screens, only opened its doors at the start of the year.
The Premier League and referees' body PGMOL trumpeted the Hub as 'the perfect space for our officials to work' and 'an environment where the best possible outcomes can be achieved' just a few weeks ago.
But faith in video referees and the integrity of the world's most popular league has been severely shaken by Liverpool forward Luis Diaz having a goal wrongly ruled out in Saturday's 2-1 defeat to Tottenham and the chaotic aftermath.
