I posted the link to the FIFA rules the other day and that’s exactly what it says. “Intentional”
Going back decades nobody has ever said any differently until Wednesday night when someone screen shot some made up rule from somewhere and everyone has fallen for it.
New IFAB laws of the game effective from 1st June 2019
The relevant bit from there:
The following ‘handball’ situations,
even if accidental, will be a free kick:
• the ball goes into the goal after
touching an attacking player’s hand/arm
• a player gains control/possession of the ball after it has touches their hand/arm
and then scores, or creates a goal-scoring opportunity
Even Peter Walton conceded on ESPN yesterday that based on these rules it would be a penalty. The other night he couldn't see the handball but having seen the full video evidence he now accepts the ball touched the arm.
The only threshold is
did it touch his hand or arm. It is as simple as that and turns it into a "matter of fact" rather than a subjective view on intent etc.
Now, these rules aren't law until 1st June.
However, the head of UEFA referees issued a directive to Champions League referees earlier in the year that they should apply ALL the new rules in Champions League knock-outs. For example, there are changes to what constitutes "deliberate" or not for penalties and based on the new definitions penalties have been awarded such as Rose and for United in the PSG game.
In conclusion, the goal should have been disallowed. VAR failed because the ref presumably couldn't see from his images that the ball touched the arm. He would have seen with the best replay.
