Rafinha is delighted to return to Barcelona.

The midfielder spent last season on-loan at Celta Vigo, where he played for new Barca coach Luis Enrique.

"I learned the game for seven years here and I'm thrilled to be back, it's a great challenge for me … I want to learn from these brilliant players," he said.

"Luis Enrique is someone who does everything to make sure he does things well."
