We hoped at least part of this was coming, and now here it is. The FA have charged Diego Costa with violent conduct for his off-camera-not-seen-by-the-referee incident on Saturday, which is great news! Yay retrospective justice! In the not-great-news department, though, Gabriel was also charged - his charge is improper conduct, following his sending off.
In addition to those charges, both teams were charged with failure to control their players. By the end of this week, all this will be sorted, as players and teams have until Thursday to respond to the charges - although Costa's been given a deadline of tomorrow night to answer to his charge.
