Hector Bellerin enjoyed a season-long loan at Real Betis last season, helping the Spanish club to Europa League qualification by finishing fifth in La Liga.
The full-back played 23 games for Betis on loan from Arsenal before returning to the Emirates Stadium as the club agreed to terminate the player's contract. Betis were interested in signing Bellerin on a permanent basis, but the Spaniard completed a shock move to FC Barcelona on deadline day.
Bellerin left Arsenal after making 239 appearances across an 11-year association with the club before penning a one-year deal at the Nou Camp.
