#3 Lionel Messi shows the Bernabeu his name, Cristiano Ronaldo responds in kind
Those two.
There's no escaping them, I'm afraid.
When Barcelona sauntered up to the Bernabeu needing a win to keep the title race alive, Lionel Messi provided it with the most sublime of goals... and then celebrated with a defiance that hadn't been seen in the Argentine... ever.
I'd written about the deeper implications of that celebration here - Lionel Messi, a dog, bronca, and the loneliness of lost innocence - but even without it, you'd struggle to see a more iconic picture than Lionel Messi looking up at the imposing mass of the Bernabeu, lifting his index figure to indicate his standing in the pantheon, asking them to read the name on the back of the shirt he was holding up for them to see.
So, of course, a few months later, when Real Madrid rocked up to the Camp Nou as reigning champions of Spain (and Europe) to play the Super Copa, Cristiano Ronaldo did the exact same thing after scoring a beaut of a goal.
