The request from the French and Spanish federations has been accepted by FIFA.
Two assistants will sit in a van outside Stade de France and watch the game live. They could intervene on contentious decisions at the request of the referee, German Felix Zwayer.
While it's great news that FIFA is finally taking this seriously, it seems a liself-defeating if the ref has to ask them to review incidents.
