I would have bought that a few years ago. But in the past couple of years, Ronaldo seems to have matured immensely. He seems less caught up in a dick-measuring contest with Messi (as many have been caught up themselves on these forums). Rather, he's looked at the evidence, the trophies, and deferred. It's kind of odd... rarely do you see that kind of respectful deference from players at his caliber.
His goal celebration seemed entirely fitting in that category: less someone acting the whiny bitch who tried to "in your face" it after failing for so long, and more someone who savored the moment while knowing how easily the roles could be reversed.
By contrast, Messi's reaction betrays no awareness nor acknowledgement of these professional subtleties whatsoever. For him, it's always more like, "I like lollipops."
