As much as we like to experience it, we like to talk about it.

So perhaps the reticence in some parts to the implementation of VAR which was recently trialled at the FIFA World Cup in Russia amounts to the danger of losing an element of controversy that we enjoy chewing over in the aftermath of a contentious decision.

Argentinian referee Nestor Pitana seemed to go out his way to make his own case against that at this year’s World Cup final when he gave France a penalty that the rest of the world would have argued somewhat vociferously against.

That he penalised the use of a hand from Croatian winger Ivan Perisic after reviewing the decision more than once on his VRU screen suggested that even with the full use of modern technology, interpretation can still ensure a sound argument ensuing.

In any case, the incident made for an interesting moment in the Celtic dressing room. Olivier Ntcham turned up for training in the immediate aftermath of the final sporting his France top, a choice of attire that was always guaranteed to incite a reaction from Croatian defender Jozo Simunovic.

"If you're French then yes [it was a penalty],” smiled Celtic manager Brendan Rodgers. “The rest of the world felt sorry for Croatia…..but our French boys are adamant it was a penalty."

Rodgers might have indulged in a chuckle at the teasing in the dressing room but as he has spent the summer plotting the serious question of how to take the Parkhead side back into the group stages of the UEFA Champions League, he believes the use of VRU at such high profile games could be a blessing.

Given the finances at stake and the thin lines between success and failure, Rodgers expects that reviewing controversial decisions could help avoid any wrong calls.

"With the money involved in the Champions League, that's a great point,” said Rodgers.

"I just think it's shown that it can work and work well.

"But of course there's a huge investment needed for it. It would be interesting, wouldn’t it, if it was used for televised games.”

When tried out in England last year the overall effect seemed to be a bit hit and miss. However, with greater exposure Rodgers believes that it could be seamlessly woven into the game.

"I thought VAR worked very very well at the World Cup,” said the Celtic manager.

"We were probably all a little bit sceptical of it at the beginning, after seeing it in England earlier in the season.

"There was one Liverpool game where there was a delay for seven minutes. People were waiting when it was in the middle of the winter which wasn't ideal.

"But in Russia is was very slick in the main and a lot of the decisions were correct and it didn't really alter the flow of the game.

"So I think it worked very well.

"There is obviously a bit financial implication involved in it.”

Rodgers, meanwhile, is wary of the effect the early closure of the English transfer window could have on Celtic. English side have until August 9th to add to their squad, a move that Rodgers believes is sensible in terms of avoiding uncertainty within a dressing room although it remains to be seen what the knock-on effect of that is north of the border.

And with clubs already showing an interest in Kieran Tierney this summer there is always the fear that a bid could come in late in the window.

"That's always the threat [in terms of late bids],” said Rodgers. “But you always have to be aware of it."

"It will probably affect us in some capacity.

"Until we actually experience it for the first time we won't really know.

"It'll just quicken up the selling or loaning of players because clubs only have until the first week in August now.

"But we'll probably know better after we experience it.

"The Premier League clubs will have to make earlier decisions on players. But I can see the concept and it is right.

"When your season starts it's always difficult when you have guys in the changing room thinking about staying or going.

"Especially when it gets into the last week, it becomes a little disruptive."
