Atletico Madrid midfielder Ardan Turan was booked for an unbelievable act of dissent in Wednesday's eventful Copa del Rey quarter-final second leg clash against Barcelona after launching his boot at a linesman in anger after failing to win a free-kick for what he believed to be a foul.
The Turkey international's footwear came off following a tangle with a couple of opponents near the touchline, and he was shocked when the assistant didn't flag to stop play in his favour.
What Turan did next can only be justified by a quick rush of blood to the head, but he'll be lucky to escape a retrospective punishment for something that could've caused serious injury.
The 27-year-old's frustration probably stemmed from the fact his side had twice been pegged back by Barca in the first 45 minutes, going in at the break 3-2 down on the night and on the wrong side of a 4-2 aggregate scoreline.
Fernando Torres had given Diego Simeone's side a 1-0 lead inside 40 seconds, but Neymar drew the visitors level minutes later before Raul Garcia's penalty put the hosts 2-1 ahead.

However, an unfortunate Miranda own goal and second goal from Neymar gave Barcelona the advantage, and minutes later Turan's fiery reaction highlighted just how highly charged the atmosphere is around the Vicente Calderon.
