This is a huge step for football. I've thought about something like this for a long time. There should also be a rule against players wasting time on the pitch when their team is leading.
Referees at this year's Club World Cup will be equipped with body cameras and instructed to implement new rules to cut down on time-wasting by goalkeepers. The 32-team competition in the United States will attempt to crack down on time-wasting by goalkeepers, awarding a corner to the opposing team if they hold on to the ball beyond eight seconds.
