The current Champions League holders, under the guidance of coach Pep Guardiola, have tested several various formations during their 2011-12 campaign.
But Busquets has insisted that the Catalans are not yet finished.
"The coaches and the players try to add variants to the team's play so we can attack better and score goals, which is the most important thing," the 23-year-old was quoted as saying on the club's official website.
"I don't know the extent of our innovation. It's for those who follow soccer history to decide whether we take football to another level."
Busquets also mentioned the importance of their upcoming La Liga derby against Espanyol, which he feels should not be overlooked.
"It's a derby and that means we have extra motivation. We'll all do what's best for the team. I believe it's one of the most difficult grounds," the midfielder said.
"They're a great team that pressures high up the pitch. Even though they've sold some players and have a young team, they're having a great season."
