What's with VAR

I've only recently got FM20, been playing FM17 for the past 3 years. So there's been some massive changes for me of course.

One I want to ask about is the VAR, after a few matches there's been comments about VAR being a factor in the game, but there was no VAR incidents to notice. Is that just how it's used in game, written in news reports, or is there actually some incident during the match that would mention VAR?

All good! Finally seen it happening during a match, I thought they'd show it with the ref walking away from the pitch or something but it's just a text display that I noticed.
