Barcelona midfielder Rafinha would welcome brother Thiago Alcantara back to the club.
Bayern Munich midfielder Thiago has been linked with a return to Barca, along with Real Madrid.
Rafinha said, "It would be great if he comes back.
"He is a player with Barça's DNA and he would be perfect. I would be very happy for him to come, although I know he is very happy at Bayern because he has the confidence of his coach.
"But he's a trained player here, with Barça's style."
