Arana, 20, became highly coveted after establishing himself as one of the best full-backs in Brazil, with his form earning a place in the Campeonato Brasileiro team of the season and helping Corinthians to the title.
The attack-minded defender was linked with a host of clubs, including Barcelona, but Sevilla have managed to secure his signing ahead of the January transfer window, reportedly paying €11 million.
He continues the club’s strong tradition with Brazilian players, after Julio Baptista, Dani Alves, Adriano Correia and Luis Fabiano all rose to prominence at the Ramon Sanchez Pizjuan.
Arana’s long-term target will be dislodging Sergio Escudero as first-choice left-back.
