Thoughts? Having seen it in action in the Women's WC I think if it's going to stay the only way I'd prefer to see it work is for each team to have say two 'challenges' per match and like cricket & tennis if you use it and you're wrong you've lost your challenge; and for the ref to use it when they want to verify a decision, otherwise I'm not in favour of remote reviews taking place during the game when the ref hasn't called for them.
