One of the easiest laws of football to enforce must be under law 12 where it states “a goalkeeper is not permitted to keep control of the ball in his hands for more than six seconds.”.
Goalie has the ball, ref starts counting 1..2..3..4 etc. at, say, 8 seconds he warns the keeper. Next time, after 6 seconds, ref blows up and awards an indirect free kick to the attacking team. Goalie will not transgress again.
It's not difficult and if the authorities don't care if that law is not enforced then it should be removed. As far as I can see, it is one of the laws where the ref does not need to apply any interpretation or assessment he just has to be able to see the kepper and to count to six.
What do you say about that Cabbie?
With due respect to Sarginson though it may be that he cannot see when the goalie has the ball in his hands as evidence has shown that he cannot see a player push a ball boy when he is staring at aforementioned player from about 12 metres away.
