Dimmed lights, dozens of screens and men with headsets huddled together... but once play starts they're shouting over each other: Inside the Premier League's VAR 'Hub' where refs made disastrous Liverpool offside decision

• e-mail

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.

PGMOL admitted that VAR official Darren England and assistant Dan Cook, who were sat in the Stockley Park control room, failed to act after Diaz's 34th-minute goal was wrongly disallowed.

Replays of the incident showed Tottenham defender Cristian Romero clearly playing Diaz onside.

The disallowed goal came with Liverpool down to 10 men after Curtis Jones had been sent off but with the scores still level.

Released audio of the interactions between he VAR officials and on-pitch referee Simon Hooper revealed those at Stockley Park believed the on-field decision was 'goal' rather than 'offside'.

This meant the VAR check was completed and by the time the error was noticed, the match had already restarted, meaning it was too late to make the correct call.

The transcript end with England saying: 'I can't do anything. I can't do anything. F***.'

The saga took another dramatic step on Wednesday when Liverpool manager Jurgen Klopp sensationally called for the entire game to be replayed.

'I can say immediately, even though some people wouldn't want me to say, not as a Liverpool manager, more as a football person, the only outcome should be a replay,' he said.

'That's how it is. Probably won't happen.'

A slick video released on the Premier League website back in August takes us inside the workspace where England and Cook made their mistake last weekend.

The room features cubicles each with three computer monitors and communication headsets where VAR officials can watch the live action and the replays necessary to help on-field referees with decisions.

Aside from the on-brand Premier League purple colour scheme and quite dim lighting, the first thing you notice is how close the officials are sat to one another.

While the Spurs vs Liverpool game was a 5.30pm kick-off and the only game taking place at that time, the chatter of all the officials huddled in the tight space when many games are happening simultaneously must certainly test the noise-cancelling qualities of the headphones.

But as well as that nerve centre for busy matchdays, great pains have been taken to provide space for officials to prepare pre-match and then unwind post-match.

There are lounges, complete with TV screens showing sport channels, a canteen, kitchen area and a fully equipped gymnasium.

Another video in which Sky Sports pundits Gary Neville and Jamie Carragher are shown around the building reveals it also boasts a massage room for the officials.  

PGMOL chief refereeing officer Howard Webb said when it opened: 'It's a cutting-edge and completely bespoke elite-performance facility, an environment where the best possible outcomes can be achieved in the VAR space to benefit the game.

'It's not only the perfect space for our officials to work when they are acting as VAR or AVAR [assistant] though, there are other areas for our officials to focus pre-game and debrief post-game, while there's a gym and a recovery area, as well as a training centre, both for VAR work and for general refereeing development.'

Premier League referee Peter Bankes says: 'What we've seen today is beyond my wildest dreams in terms of facilities. The Hub it self is fantastic - it's quite futuristic and professional.'

Stuart Attwell says: 'I think it's a fantastic advancement for us. I think it's going to put us in a real position to be able and deliver world class performances in a world class competition.'

However, just one contentious incident has gone a long way to undermining faith in the VAR system.
