Atletico Madrid assistant coach German Burgos went ballistic along the touchline after Atleti striker Diego Costa was booked for simulation Sunday against Real Madrid.
Earlier in the match, Costa had a penalty appeal turned down after going to ground under a challenge by Sergio Ramos.
While the first incident perhaps should have earned Atleti a penalty, the latter was less clear-cut.
Burgos didn't see it that way, however, and that's not necessarily surprising. Burgos, as you might recall, once threatened to rip off Jose Mourinho's head.
