Costa looks like he's done a few lines at half time.
Chelsea have subbed him early so he can go and take a **** in the middle of Arsenal's changing room.
The ref ruined the game, pointless since half time.
Yes Costa should have been off and the ref missed it, they can't see everything.
The issue is Gabriel being an idiot, he deserved his red card. You can't excuse it just because Costa WASN'T sent off. I hate Costa as well, but the Arsenal players should have just got on with it, there was no need for them to have to go down to 10 players.
Arsenal fans, just accept the fact Gabriel was a fool.
(I am not a Chelsea fan, I wish Costa was out for the rest of the season).
