Rahm was a joke then.
Something needs bringing in, penalty shot for not shouting fore when clearly heading into the crowd rather than the arrogance that was on display then by Rahm just throwing his club to the ground which like racket abuse, should be penalised also.
I don't subscribe to the guff the crowd wouldn't hear it, when it is shouted you see them all turn and crouch, it needs to be shouted, period.
