The 26-year-old left Arsenal on the final day of the transfer window to return to La Liga.
Bellerin took a pay cut before joining the Spanish giants and claims the “love of sport, of the club, is being lost”.
“It is clear that money is something important, because it is our job. But I think in football that love of sport, of the club, is being lost.
“And for me, after having understood and had that feeling since childhood, there are things that you put first. This past year and a half has made us rethink many things.
“For me and for everyone it was an effort to carry out the operation, not only from the point of view of money. Also how much it cost us to get here. In the end, those efforts pay off and I had other priorities when making my decision.”
Bellerin also admitted he's in the dark of where he will continue with his career next year if his loan deal comes to an end at Betis though will still have one more year left on his contract with the Gunners next summer.
“I don’t know, but I’ve always said if I didn’t want to be here next season, I wouldn’t have come from the beginning.
“There are many things to be decided but what I want to do is enjoy this season that I am here. And what has to happen will happen.”
