Zaaboub signed for the Saddlers on a free transfer from Swindon last season.
He told the Express and Star: "I'm not staying. I am in a situation like I was last year. Walsall offered me a one-year deal and I played for a season, then they offered me another year.
"I have no stability. If I am signing a year's contract every year, then I can wait a few more months.
"I know I can play at a higher level so I am going to try, I can wait for better opportunities."
