In the future, I'm sure video technology will be brought in. The video ref will be able to overrule decisions to allow goals etc... And all major decisions - red cards, penalties, will involve mandatory consultation of the video ref, all in conjunction with GLT (not a type of sandwich!) and a challenge system available to captains similar to that in tennis. However, this would never possibly happen with the clueless buffoons currently in charge of the English game, who insist upon making life 10 times worse for referees by refusing to allow them elementary help, or to accept that referees will occasionally make mistakes, and get rid of that bloody ridiculous rule where players can't be retrospectively punished if the referee books the player. The introduction of GLT is a baby step in the right direction, but it is of course only coming in the premiership and, naturally, must be funded by the clubs.
