The friendship Luis Suárez and Lionel Messi formed as teammates is put on hold when the European season comes to a close and the competition heats up. They become rivals as they train for the 2018 FIFA World Cup and when Messi doesn't measure up to Suárez on the exercise bike, he decides to unfollow him on Instagram, a move that leads the men who used to take selfies together out on the soccer field to a full-blown feud. In retaliation, Suárez sells Messi's jersey for $2 and they continue to try to one-up each other. While Suárez signs a jersey at the stadium, Messi signs someone's back. Gatorade declares that everything changes except what's inside the two players as they gulp down the sports drink right before taking the field.
