Arsenal centre back Gabriel Magalhaes delivered a brilliant response when he found out his second headed effort was ruled to be an own goal.
The Gunners got back to winning ways with a commanding performance against a poor Crystal Palace side.
Gabriel opened the scoring with a powerful header from an inswinging corner and he thought he had grabbed the game's second 20 minutes later.
However the Dubious Goals Comittee awarded the goal as a Dean Henderson own goal, denying the Brazilian his second of the day.
Upon hearing the goal was not his, Gabriel produced a good natured reaction when stood alongside international teammate Gabriel Martinelli, who came off the bench to score a brace.
