The thing is that they don't have to be in control of the ball or directly score in the literal sense. Creating a dangerous situation out of the ball touching an attackers hand immediately results in a handball with no questions asked as per the new rules.
The thing is, that's not what the new rules actually say.
Handling the ball
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
At the time TAA handled the ball, what Silva did wasn't a handball offense. It was a potential offense in the same way a guy making a back post run from an offside position doesn't commit an offside offense until he actually becomes active in the play.
If TAA doesn't handle the ball, Sterling lets the ball go past him, City picks it up out wide, and then develops another attack by recycling the ball around the edge, it wouldn't be a handball offense.
The new handball rules explicitly require either the ball to go in the goal or for the attacking team to gain possession.
Under the interpretation you're mentioning (that Clattenburg supports), once the ball touches the attacking team's hand/arm, the defending team could do literally anything they wanted to either break up the attack or start a counter and not be punished for it on VAR, which is clearly absurd.
As for the foul things...I mean you see it happen on the field all the time where a foul is committed after another foul
Yes, that happens all the time, and if the ball actually got to Sterling and TAA handled it after that, the new rule would clearly apply.
The one thing I think most people agree on is that the PGMOL's reason for not calling the TAA handball was terrible. The difference you and I have is one of the interpretation of the rules. The PGMOL's defense of VAR is just ignoring what basically every person who looked at the play called a handball. If the ball went to TAA after deflecting off of Silva's knee instead of hand, does anyone really believe it shouldn't be called under the rules?
