Messi photobombing Cristiano Ronaldo perfectly sums up their entire relationship

Forget that classic image of Pele and Bobby Moore embracing. Forget that wonderful shot of a forlorn Zinedine Zidane shuffling past the World Cup trophy. You can even forget that picture of Vinnie Jones grabbing Gazza by the goolies.

At the draw for the 2015/16 Champions League group stages, one lucky photographer took perhaps the greatest photograph in football history.

True, it might not be as iconic as some others. But Lionel Messi photobombing Cristiano Ronaldo is almost too wonderful.

This one moment perfectly encapsulates the rivalry between the world's two best footballers.

Cristiano Ronaldo should be the focus of the football world's attention. Just look at him sitting there. He's handsome, well dressed, supremely talented… he's the perfect athlete. And at first glance, it certainly seems the spotlight is focused on him.

But wait. Who's that in the background? It's someone shorter, less handsome and without the rippling abs - someone who, at first glance, shouldn't really even be comparable to the great Cristiano - completely upstaging the Real Madrid master with a brilliant combination of funny facial expression and comic timing.
