Real Madrid sealed their 32nd league title with a 3-0 win over Athletic in their third to last match of the season. Athletic's Javi Martinez was sent off in the 72nd minute for his second handball and after the final whistle blew and Madrid began their celebration at the San Mames, Martinez re-emerged to have a chat with Cristiano Ronaldo.
Feeling the furious joy of winning his first title in Spain (and fourth of his career), Ronaldo shouted at Martinez and gave him a "shove it" gesture before going on to celebrate with his teammates. Though Martinez was the target of this gesture, it was probably intended for many, many more people.
UPDATE: Martinez reportedly told Ronaldo, "Don't celebrate too much, I'm a World Cup champions and you're not, clown."
