This was peak Diego Costa.
The Chelsea striker, whocould easily have a post-football career as a WWE bad-guy, was at the centre of the action at the Emirates today.
Costa was involved when Per Mertesacker got sent-off after 18 minutes. The Arsenal defender missed his tackle on Costa, who was racing onto a through ball from Willian. But many Gunners' fans felt the Brazilian born Spain international dived.
Five minutes later, Costa scored what proved to be the winner, turning in an excellent cross from Branislav Ivanovic and leaving Per Cech with no chance.
The Chelsea striker was substituted after 70 minutes, but his work was done.
He's definitely public enemy number one with Arsenal fans. And most on Twitter.
