Ceballos joined Arsenal on a season-long loan from Real Madrid in the summer of 2019 and capped an impressive first season in North London by winning the FA Cup.
The 24-year-old had that loan spell extended for another year at the start of this season but the Spanish international has not had a consistent run in the Arsenal team this time round.
Ceballos has made 37 appearances in all competitions for Mikel Arteta’s men and is yet to record a goal or an assist.
Having tasted both the Premier League and La Liga with Real Madrid and Real Betis, Ceballos is convinced his talents will be better served in his native Spain.
"I've had a bad time because I didn't have the consistency I had last year," Ceballos told Onda Cero ahead of Arsenal's Europa League semi-final tie against Villarreal on Thursday.
"These last 5 or 6 games I've played at a good level.
"To be honest I like La Liga a lot more. The Premier League is more complete but with my style, La Liga is much better for me.
"Another loan would be difficult from both sides, for Real Madrid and for me."
"I'm about to turn 25 in August and I have to settle at a club where I feel important, that's what I'll look for," he added.
"I have a lot of affection for Betis, I'm a Betis fan, I watch every Betis game, [Manuel] Pellegrini is a really good coach who I like."
