Goal kick was more advantageous, nothing came from the offside so it didn’t need to overrule the on field decision.
I’ve quoted Jinky but I’m sure Bennett will reply.
I think it’s a penalty, but given the decision by the ref the only call I can fathom is they’ve decided the rangers player must have fouled him, but the goal kick is more advantageous.
But there’s a Kyogo wonder hit.
