We can’t help but cheer for Pepe (although his little headbutt looks fake too!) … Also, you will find a plausible theory explaining why players have an incentive to fake injuries in Michael Gard’s excellent essay Faking it: why football players feign injury. Here is an excerpt:
The first thing to say is that feigning injury in football today has reached truly epidemic proportions. A Wall Street Journal article [mischievously titled “World Cup Flopping Rankings”] reported 132 minutes of “writhing time” in just 32 World Cup games. Of the 302 separate instances of players appearing to be very seriously hurt, 293 of them were up and playing within seconds. Just nine were actually injured.
Don’t all these fakers deserve a post-game red card, starting with Thomas Muller?
