DAZN refereeing expert Luca Marelli explained that it was disallowed directly by the VAR without the need for an On-Field Review by referee Maria Sole Ferrieri Caputi because a handling offence directly leading to a goal is automatically punished, whether it is considered to be intentional or not.
As this was an objective ruling confirming the touch on the arm, the VAR could over-rule the goal from the booth.
It is also arguable that Sverko fouled Bisseck by jumping with both arms on his back, but the handling offence is sufficient to disallow the goal.
