Signed from Barcelona last summer, the midfielder was immediately loaned to Al-Okhdood of the Saudi Pro League.
However, he will be due back at Betis for preseason and told Marca: "The idea is now to rest for ten days, which I think I deserve, and prepare now to be 100% in the preseason with Betis.
"No, I haven't spoken to anyone, but wow, I signed for five years, I left with the idea of having an experience outside and being able to return, and well, now let's think about the preseason, which is what I have in front of me."
On his season with Al-Okhood, Collado said: "The truth is that as we have finished the season very happy, personal, collective, team issue as well.
"I was coming from a bit of a screwed up season there in Elche, on a personal level as well, when I had a long-term injury. And well, the truth is that, as I told you, happy to achieve the team's goal.
"Personally, it ended at a very good and happy level, I'm happy."
