Jurgen Klopp has called for VAR improvements to be made after goalkeeper Robert Sanchez avoided a red card in Liverpool's 2-0 win at Brighton.
The Seagulls goalkeeper was beaten to the ball by Luis Diaz for the opening goal in the first half as the Reds went to within three points of Manchester City in the Premier League.
The goal came at a price for Diaz, though, who was taken out by the goalkeeper's high challenge that left the Reds star in need of treatment from the physios.
After a VAR check for a potential sending off, it was judged that Sanchez did not deserve a red card and while Klopp said he was yet to see a replay, he believes adjustments still need to be made over the use of the technology.

"I haven't seen it back so I don't know if it was a red card or not," Klopp said.
"It's a good example, a very good example for VAR and the issues we still have.
"The thing is that, it was a top goal and (referee) Mike Dean, how it should be on the pitch, he sees the goal and maybe thinks about a red card but knows there is VAR.
"So the linesman [doesn't flag], no offside, goal. Now we have the problem with this phrase 'clear and obvious'.
"That is the real problem, this phrase, because everyone has asked me today and I didn't start the conversation, everyone has asked me if it was a red card or not.
"You know when you get these questions that most of the people think it was a red card. So you think 'OK, it was a red card.' Everyone thinks it, so for what reason could it not be a red card, then?
"VAR look at it and there is only one reason for it - 'clear and obvious'.
"So we have a referee who might not look at it and make a decision because he thinks 'why should I? There is someone with a screen who can tell me who saw it.
"Maybe Mike thought it was not a penalty and it wasn't a red card. It's not 'clear and obvious.' You can see it like this but it happens constantly."
Klopp added: "Why do we have these discussions after games?
"We had a conversation with (PGMOL manager) Mike Riley a few weeks ago with all the managers and spoke about it. 'Clear and obvious' is, from our point of view, the real problem.
"Because 'clear and obvious' is right or wrong, it is not clear and obvious.
"So no-one should feel like overturning someone's decision if the VAR is a part of the team of referees and not someone from outside who thinks he might embarrass the ref on the pitch with his decision, that would help as well.
"It's not important today, we scored a great goal but in general, there is a lot of space for improvement, for sure."
