No. Both Xavi and Iniesta were considered to be extraordinary talented from the time they were just kids. Iniesta was brought to Barcelona from Albacete because he was a star in some big tournament when he was 12 years old. By the time they both had reached 18, they were no longer playing for the B team, and by the time they had reached 22 years old (Rafinha's age) they probably had close to 100 games each for the first team. Even though Iniesta wasnt a fixed starter yet (because of certain Ronaldinho and Deco), he was always the 12th man of the team. They were both world class players by their early 20s, no doubt about it. Of course, not all players are as talented as they were at an early age, and some players take longer to truly shine, and then just explode, like Busquets, who no one knew anything about before he suddenly "came from nowhere" and cemented a starting place for Barcelona.
