So they look at handball in immediate lead up to Brighton goal.
The ball comes to Rutter who aims to control it with his thigh but mis-controls and it goes upwards and catches his arm and changes the travel of the ball 90 degrees or more so he is able to shoot at goal.
It gets saved and then from a second or two more of play he gets another chance at shooting and scores.

It’s called accidental handball and it’s allowed .

I’m totally lost, how can it be accidental if the ball catch his arm changed the direction of the ball so much ( he wouldn’t have been able to have his original shot if it had not hit his arm ). As the ball would have continued from his thigh away from him and towards a West Ham defender.

Either way Brighton stay below us but honestly struggling to understand any of the decision
