Kaka's game was about explosion, something you lose with age. Ronaldinho lost motivation, basically. Won it all, and wanted to chill and just play for fun, as he is still doing it. Iniesta is on a decline since last season, when he was 29. He still shows some glimpses, but I doubt he'll be what he once was. And he's spanish.
Not to mention his knee injuries.
