The midfielder is confident of the Brazilian making a big impact at the Nou Camp.
"He won't need much time to adapt. When you are one of the best players in the world and you come to a team like ours, you adapt quickly. He's coming from a different kind of football but anyone can see that he has quality and talent. He'll do a lot for us," said Iniesta.
"Everything about his signing is positive for us He's closer to Dani and Adriano right now, but it's only natural that he'll gradually start feeling more at home with the group. We're a very healthy group in that respect."
