Barcelona coach Luis Enrique wants to return to Celta Vigo to strengthen his midfield.
Sport says Enrique has recommended the signing of Celta youngster David Costas to the Barca board.
Enrique worked with the Spain U21 international while in charge of Celta and gave Costas his first team debut.
In his final weeks with Celta, Enrique said of Costas: "He's a natural. He has great self-belief and an amazing presence."
Barca will have to find €10 million to prise Costas away from Celta.
