In the Telegraph, they said that no player should be able to touch an opposition player at all.
I think that this is a good idea. I am fed up of players dangerously pushing each other just to wind each other up:
No hands
There is one very simple change to the laws of football that would make a world of difference: banning players from putting their hands on each other. They can no longer grab, hold or place their arm across an opponent. Inadvertent contact, when going for the ball, such as challenging for a header when needing to use an arm for leverage, would be allowed as long as it is brief and only lasts while the ball is there. Certainly not before. They would not be allowed to hold. Any prolonged contact would be an offence. Simple as that.
