Yeah the technology itself works because there wouldn't have been any doubt if it was in place.Showed it worked ?? Buy going with the original umpires decision because they didn’t have the correct technology in place to 100% confirm the decision like what the system was actually put in place for yeah that makes sense!
Just because it wasn't available yesterday doesn't mean you have to get rid of it everywhere like you're proposing. The goal review technology has been really good this year when it is available.
