VIDEO: Atletico Madrid go down a man, Arda Turan throws shoe

Forty-five minutes of exciting football quickly turned sour after Atletico Madrid found themselves down a man heading into the second half of their Copa del Rey clash with Barcelona.

The scenes at the Vicente Calderon became even uglier when a shoe was thrown at a linesman shortly after halftime.

The game began its tailspin when an off-camera altercation took place between players in the tunnel after the first interval, resulting in Atletico going down a man when midfielder Gabi picked up his second yellow card.

Shortly before the incident, however, tempers between the two sides flared, as Fernando Torres and Neymar were seen exchanging words. Torres even delivered a shove that went unpunished.

The situation took a strange twist shortly after the resumption of the second half, when Arda Turan, for some unknown reason, chucked his left boot towards the linesman. Luckily for him, he was only shown a yellow card for his moment of madness.
