Sao Paulo: Mexico's national soccer coach Miguel Herrera just can't keep his joy bottled up, and his enthusiasm has made him one of the most entertaining and popular figures of the World Cup and an Internet sensation worldwide.
Memes of Herrera flood the Web, like one that shows his hair catching on fire cartoon-style. In one picture, he playfully sticks out his tongue while he photobombs three members of his team on the pitch. In a video, he dances happily to Spanish ska music.
