Cristiano Ronaldo received a red card during Sunday's El Clasico against Barcelona, but the Real Madrid star didn't really deserve one for all that happened before the card was given. He was (rightfully) booked for taking off his shirt during a goal celebration, which happened to be a jab at Barcelona and Lionel Messi. The second yellow came two minutes later when the referee thought he dove inside the box, which actually didn't look like much of a dive.
As you can imagine, Ronaldo was livid, and what happened next could result in a lengthy ban.
