We're still some way off getting VAR right. God help us all if this current set up ever becomes standard practice in every game. It's not really the system we hoped for and spent two decades calling for, but it's still wet behind the ears and there's plenty of scope for improvement.
So I wonder, what other types of technology could one day come into the game for better or worse?
Most clubs these days make their players wear those things that look like sports bra's, which I think are performance monitors that collect data from each individual player, of their performance. Like an advanced FitBit. - Good idea.
Referees and linesmen have earpieces so they can communicate easily - good idea, although they may as well not bother at times.
But what if players wore earpieces or headsets of some sort, so the manager can easily relay instructions to any individual player at any time? Would this improve the game or just complicate it? I don't think we're ready for it yet, but in the future who knows?
Maybe players could one day players could wear some sort of sensors under their kit and boots, combined with a sensor inside the ball, that could instantly and accurately inform the officials exactly who's throw in it is, or whether it's a corner or a goal kick. Those little decisions can have a huge impact on games if they're wrong.
