Cristiano Ronaldo Juggles Tennis Ball on Chinese Television Show

Ever tried playing keepy-uppy with a tennis ball? (Spoiler: It's very hard.)

But Cristiano Ronaldo made it look easy when he appeared on a Chinese television show.

The Real Madrid and Portugal superstar, who will take on Belgium with his national side on Tuesday night, kept the ball in the air and even pulled off a behind-the-back move—pity his team-mate couldn't keep the juggle alive.
