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.

Betis, who also won the Copa del Rey last season, couldn't bring Bellerin back to the club on a permanent basis, according to president Angel Haro. The Spanish club have experienced financial difficulties and narrowly avoided Financial Fair Play sanctions last season. They would have had to sell a player to bring Bellerin in.
"This year [signing Bellerin] was unfeasible," Haro told Estadio Deportivo. "As our theoretical [salary] limit was exceeded, it would not make sense. That's why the objective was to keep the group [together]. It didn't make sense to add someone."
Bellerin could feature in Barcelona's squad for the first time when they face Cadiz on Saturday. He has been included in Barcelona's 31-man Champions League squad but didn't feature in their 5-1 win over Viktoria Plzen.
