Hi guys. Before the second goal was scored by Mo Salah against Man U, the referee raised his arm and made the offside signal therefore resulting in an indirect free kick. However, the keeper Allison collects the ball with his hands and then directly plays it out of his hands via a long kick to Mo Salah who then scores. Shouldn’t Allison have taken the kick off the ground? Can advantage still be played when the referee has already made a signal for offside? Any clarification from the laws on this incident please guys?
