Yeah, Iniesta's days of being criminally underrated are over considering he scored the winning goal in the motherfucking world cup. Discounting all other accomplishments that alone makes him an eternal legend, he's a national hero in Spain and while he's still underrated by the English language media, the past few years have made sure he isn't an unknown.
He's still a little understated because he's so damn humble and his injuries have made him overshadowed by a few others for consistencies sake, but he's hands down the most clutch player on the team. It's fair to say Xavi and Messi are more important overall, but Iniesta alone puts both club and country over the edge.
