He's just faking an injury so he doesn't have to waste time for NT friendlies when he can eat some burgers with his family at home. I don't think I have ever seen him injured.
Such a Suarez thing to do. Misses the easy ones and then scores that. Glad to see his general play has improved greatly over the last couple of games. If he starts scoring again we're in great shape for the business end of the season.
