I have strange feeling watching these old videos. My first thought is why ref isn't going to watch VAR and only later I realize that we have VAR just for few years so far .
You're right I just looked it up, Hawk-eye only introduced in 2013 in EPL. In my mind, for some reason, I thought it was soon after all those ghost goals of early 2010s but yeah now that you mention it, it took some big, big bad calls at international level for this tech to be implemented.
It's one of the few digital techs I've really had no issues with. Doesn't interfere with the game, actually helps resolves decisions faster and more accurately, and is totally in the spirit of the game.
Of course, tech is not perfect, remember last season Covid restart? Can't remember which game now but a goal so clearly crossed the line and hawkeye didn't see it when everybody and video did haha.
