Sevilla have struck a deal with Barcelona to bring right-back Aleix Vidal back to the Ramon Sanchez Pizjuan for an initial fee of €8.5million, potentially rising to €10.5m.
Vidal signed for Barca in 2015 after just a single - albeit impressive - season with Sevilla, who were reported to have collected €15m for him.
Barca brought Vidal in as competition at right-back for Dani Alves, but due to a registration ban he was unable to play until the second half of 2015-16.
A hamstring injury disrupted the end of his season, but there were general suggestions Barca were ready already to sell Vidal ahead of the 2016-17 campaign.
He stayed but made just six appearances all season in LaLiga, as Sergi Roberto became first choice on the right side of defence.
Vidal featured 15 times – mostly from the bench – last term and Sevilla's interest again became known, as Barca's asking price reportedly came down.
The 28-year-old won the Europa League and was capped by Spain during his previous Sevilla spell.
He is set to sign a four-year deal and will become Sevilla's sixth permanent signing of Pablo Machin's reign after Ibrahim Amadou, Joris Gnagnon, Tomas Vaclik, Roque Mesa and Sergi Gomez.
