fair decision IMO, he was the last man, if it were a crystal palace player, we'd all be calling for a red.
Foy having a mare Realised he's made a mistake with the red and now trying to make amends by not giving a foul against Gnabry.
Red card isn't really that unjust, he was the last man...We really only have ourselves to blame, if we didn't start the first half so poorly, the game could've and should have been over before Arteta was ever sent off.
