A TV commentator for a recent top game said, 'It's about time they changed the handball law to stop all this confusion - if the ball hits a hand or an arm in the area it should be a penalty'.
What a load of rubbish! Handball has always been an offence only if it is deliberate and it is a nonsense to make it otherwise. If the 'deliberate' part of the law is taken away players could purposely kick the ball at another player's hand or arm in an attempt to get a penalty or a free kick.
A recent new trend in the modern professional game is for defenders to put their hands behind their backs when challenging for a ball when it is about to be crossed, particularly if they are in the penalty area. This should not be necessary and natural arm movements should never be penalised in a ball to hand situation.
If players feel that it is necessary to put their hands behind their backs to avoid the risk of a penalty being given in an accidental handball situation then referees are, in my opinion letting them down!
When you see the defenders putting their hands behind there backs in the penalty area, I don't think the refereees are letting the players down. I think the defenders don't want to risk any form of handball (deliberate or not deliberate) because we all know if it was accidental hand ball, 11 players are going to scream out hand ball and demand a penalty. (Obviously a quick and firm voice by the ref stating "accidental, play on" should quell the 11 players).
So I feel the defender is thinking it's better to be safe than sorry by placing his hands behind his back. It also cuts out a natural reflex reaction by the defender of deliberate handball.
