Argentine superstar Lionel Messi did not feature at Euro 2012 this summer because, well, he's not European.
Still, he's the best in the world, and few would argue it.
Spanish star Rafael Nadal isn't ranked No. 1 anymore, but he is a two-time Wimbledon champion and he did defeat Novak Djokovic in the French Open final this year.
Alas, we didn't see much of Nadal this summer at Wimbledon. He lost his second-round match to the Czech Republic's Lukas Rosol.
Much like Messi, then, Nadal's talents didn't play out on the grandest stage this summer. It's an imperfect comparison, however, because Messi had no chance to play at Euro 2012.
Having said that, there's more.
Like Nadal's Wimbledon loss, Messi and FC Barcelona suffered a disappointing exit from the Champions League semifinals this past spring, before losing the race for the Spanish league title to Real Madrid as well.
