Rodgers asks UEFA for VAR use in the Champions League

VAR was tested in various domestic competitions during the past year, but the introduction of the system has been met with scepticism.

The most high profile usage was during the World Cup in Russia.

While the VAR panel's work in Moscow didn't completely eradicate controversy, there were more correct decisions made overall.

Now, with Europe's premier club competition around the corner, and with the business side of football being increasingly important, VAR could be an important introduction.

Brendan Rodger's will be hoping that Celtic will make a big impact in the competition, and the manager believes that VAR could help.

"I thought VAR worked very well at the World Cup," he said.

"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 it 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."

When he was asked whether money in the Champions League will be key in keeping refereeing errors to a minimun, he said:

"There is obviously a big financial implication involved in it."

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

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

"But of course there's a huge investment needed for it."
