Just watched Italy beat Czechs, and saw something which I've seen happen thousands of times in football..........
.......a player collapses in apparent agony on the field, and stays down for a minute or so. He limps off/is stretchered off, but within seconds of reaching the sidelines, is waiting to run back onto the field of play, having received the legendary douse of cold water, and all the medical properties it contains.
How about this?
Any player who is injured badly enough to need to leave the field of play is not allowed to return until 3 minutes have passed.
If the player really is injured, then waiting 3 minutes to see the extent of the injury is a good thing.
If the player is faking it to waste time/get a player booked, maybe this 3 minute system will be a strong enough deterrent.
What do you think? Any reasons I havent come up with as to why this wouldnt work?
