It's used successfully in American Football and Rugby but in our British leagues the bosses don't seem to want to implement it properly. Think how often this season it mightbhave meant different results in our league. The bitter hivee bastards would have a few players sent off, the bheasts from the east dembele(500,000,000 d$) would have been picked up diving into the box, broonaldo would see red every couple of weeks.
VAR is a good thing but we're years late in bringing it into football because of dinosaurs who claim it'll slow things down or cut the emotion. Just ask anyone who follows the NFL or Scotland in the Rugby if it slows the game down or reduces the excitement.
