Saying Rivelino, Robben and Ronaldinho don't fit together is the same as saying Iniesta, Neymar and Messi wouldn't fit together, in short, it's plain wrong. Rivelino was a playmaker, a real playmaker at that. Plays further than the midfielders, but not exactly in the 'hole'. That's where Dinho comes in as he was more of a trequatista, who used to have the capability to move wide, and Robben, a wideman who specialized in goals, he'd love to play with these as his job would be much easier. It's the perfect set up really.
