Part of the problem, directly associated with the handball is that people don't know the law and its wording, which is this:
It is an offence if a player:
deliberately touches the ball with their hand/arm, including moving the hand/arm towards the ball
gains possession/control of the ball after it has touched their hand/arm and then:
scores in the opponents’ goal
creates a goal-scoring opportunity
scores in the opponents’ goal directly from their hand/arm, even if accidental, including by the goalkeeper
It is usually an offence if a player:
touches the ball with their hand/arm when:
the hand/arm has made their body unnaturally bigger
the hand/arm is above/beyond their shoulder level (unless the player deliberately plays the ball which then touches their hand/arm)
The above offences apply even if the ball touches a player’s hand/arm directly from the head or body (including the foot) of another player who is close.
Except for the above offences, it is not usually an offence if the ball touches a player’s hand/arm:
directly from the player’s own head or body (including the foot)
directly from the head or body (including the foot) of another player who is close
if the hand/arm is close to the body and does not make the body unnaturally bigger
when a player falls and the hand/arm is between the body and the ground to support the body, but not extended laterally or vertically away from the body
One might argue that the handball created a goalscoring opportunity, which would be pushing it, as there is another 100m or so and touches by opposition players before it goes in, but I can't see how any of that applies to the incident.
This is not, much to my chagrin, a VAR issue. It's a pundits / players / managers not knowing the lawas of the game issue.
