Barcelona have loaned Marc Cucurella to Getafe only two days after signing him back from Eibar.
Cucurella caught the eye in his loan spell with Eibar last season and scored in a 2-2 LaLiga draw with Barca in May.
Eibar took up the option to sign him for €2million but Barca inserted a €4m buy-back clause in that deal, which they activated on Tuesday.
Cucurella, who can play as a full-back and a winger, had been linked with Sevilla, Real Betis and Bundesliga clubs Eintracht Frankfurt and Borussia Monchengladbach.
But he will be playing his football for Getafe in 2019-20 after they agreed a temporary deal with the option to make it a permanent one.
Cucurella made 31 LaLiga appearances for Eibar last term, scoring once.
