He's still unstoppable (as much as he was then anyway)
He's just a lot better in other departments such as playmaking and just in general decision making etc.
Disagree, he doesn't have the top line speed to run away from the better defenders now. And top line speed is crucial in the biggest games. He still has a huge impact because of the other facets of his game, but he also has Neymar and Suarez to pass and work with. Five years ago, he could take a ball in midfield and score. These days, he needs good players to finish off his always-brilliant passes.
