VAR decisions served up several moments of high drama in Russia three years ago, with holders Germany’s hopes dashed in the group stage after Kim Young-gwon’s stoppage-time goal for South Korea was awarded, having been initially ruled out for offside by the linesman.
Iago Aspas benefitted from a similar last-gasp video intervention as his flick was deemed onside after a review, seeing Spain defeat Morroco to take top spot in their group.
Meanwhile, France received a slice of luck in their opening game when the referee opted to award a penalty to Antoine Griezmann after consulting the pitchside monitor and the eventual champions went on to beat Australia 2-1.
The technology will no doubt play an influential role this summer, with moments of ill-discipline, contentious handballs and various penalty appeals to be scrutinised in detail.
Here are the officials who will make those crucial decisions:
