A hand ball along the goal line stops the ball from going into the net. It stops a goal scoring opportunity (the key phrase here). If the handball was away from the goal line it's not a definitive goal scoring opportunity and then the referee must decide if it was intentional.
Alen, how you base Rosetti's decision on something you cannot possibly know?
I think when FIFA's official explanation comes out it will say "sending off due to stopping of a goal scoring opportunity".
But this rule is better for that, dammit:
* denying the opposing team a goal by deliberately handling the ball
Why use a rule that talks about a goal scoring opportunity, when we have a rule that speaks about denying a goal by handling the ball?
And the rule you bolded says:
denying an obvious goal-scoring opportunity to an opponent moving
towards the player’s goal by an offence punishable by a free kick or a
penalty kick.
So what's an offence punishable by a free kick or a penalty kick?
These are:
Direct Free Kick
A direct free kick is awarded to the opposing team if a player commits any
of the following seven offences in a manner considered by the referee to be
careless, reckless or using excessive force:
• kicks or attempts to kick an opponent
• trips or attempts to trip an opponent
• jumps at an opponent
• charges an opponent
• strikes or attempts to strike an opponent
• pushes an opponent
• tackles an opponent
A direct free kick is also awarded to the opposing team if a player commits any
of the following three offences:
• holds an opponent
• spits at an opponent
•
handles the ball deliberately (except for the goalkeeper within his own
penalty area)
--------------
In every case it speaks about handling the ball deliberately.
The rules are pretty clear so I don't see why do we have to interpret them.
The only question here is what is a deliberate handball. That's not explained so it's up to the referee to decide. Rosetti decided that it was a deliberate handball and I think he was wrong.
