The rule is neither mindboggling, nor dictates intention. There are three conditions that will lead to a handball verdict if EITHER ONE are met:
- deliberately touches the ball with their hand/arm
- touches the ball with their hand/arm when it is in a position that makes their body unnaturally bigger and that position is not the result of their body moving fairly as part of play
- scores a goal against the other team with their hand/arm or scores immediately after the ball has touched their hand/arm (even if the touch was accidental)
For the first condition: If you use your arm to protect another part of your body from the ball, the touch is definitively deliberate - otherwise the protection wouldn’t work, would it?
Someone seems to have the impression that the rules allow for using arms to protect from the ball. This is allowed for nowhere in the rules, which has been pointed out by IFAB and others several time in directive statements.
For the second: His arms are clearly in an unatural position for anything else than blocking something. They are not glued to the body, you clearly see them sticking out in front of the body, towards the ball, making his body bigger in that direction. It might have hit his chest if his arms were in a natural position, but obviously the bounce would have been different. Now, they fall down into his feet, giving him a goal scoring opportunity even.
The breach of the third condition is equally ovious, but a good lawyer or a bad referee might ttwist it. ‘Even if accidental’ it specifies, when he scores immediately after. He scores two or three touches after. If anyone wants to argue that ‘Maguire didn’t score, it was deemed an own goal’, it is both evidently against the spirit of the law, and also extremely doubtful interpretation of the rules, as wether a deflected shot is accounted as a players goal or as an own goal is not part of the regular football rules nor in the referee’s remit. It’s for a committee and has nothing to do with the outcome of games.
I would say it is a blatant handball according to ALL THREE of these conditions, and in fact, only ONE of them needs to be met for the rule to have been broken.
Appologies for the capslocking.
