The technology, using video replays and off-pitch referees, has been developed to help officials make better decisions, therefore improving the quality of matches.

They look at goals scored, penalties awarded, straight red cards and cases of mistaken identity, when a player awarded a yellow or red card is not actually involved in an incident.

Australia, Brazil, Germany, Italy, the Netherlands, Portugal and the United States were among the first countries to have conducted tests.
The first international in which the technology was tested was a friendly between Italy and France in September last year.
A final decision on the introduction of this technology will be taken by world soccer's governing body FIFA in 2018.
