The interesting thing here is if the ref thought there was a “ clear goal scoring opportunity “ he almost probably would have played advantage. The fact he blew suggests that he didn’t.
Interestingly if he had played advantage irrespective of the outcome of that phase of play Silva couldn’t have been sanctioned
Irrespective heres what refs are told to factor into such incidents point one and two are the two that would tip it in my opinion

1: The distance between the offence and the goal. The closer it is to the penalty and goal areas the more likely the criteria would be satisfied. It’s not only the proximity, but also the area of the pitch, centrally in and around the penalty area is likely to satisfy the criteria, being right out on a touchline near the corner for example wouldn’t.

2: The general direction of play. If the striker has his back to goal or is side on looking to play the ball to an opponent then it will not fit the criteria for DOGSO. He needs to be in a position to be able to be about to take a shot or in the process of lining up a shot.

3: Likelihood of keeping or gaining control of the ball. This can be applied equally to the striker and to the defender. In relation to the striker, he does not have to have the ball actually at his feet, he could be running onto a pass from a team mate that, without the action of the defender/goalkeeper, he would have collected and had a shot on target, for example. In relation to the defender he needs to have a chance of winning the ball, for example by a clean, well timed tackle. If the striker has got away from the defender and the only means to stop him getting a shot away is to push him over or pull him back then the defender does not have any possibility of playing the ball and therefore no chance of “gaining control of the ball”.

4: The location and number of other defenders, which includes the goalkeeper. There is no set distance specified but the general rule is that if there is a covering defender or goalkeeper within range to make a tackle then the criteria for DOGSO are unlikely to be met. If the goalkeeper is stranded, has already committed to diving one way, leaving the player the opportunity to chip over him or shoot the other side of him or is the player making a last ditch tackle then the DOGSO criteria is liable to be met. If another defender, including the goalkeeper is in a close enough position to make a lawful tackle or attempt a save then the criteria will not be met.
