Zoet was a target for Palace when Dutchman Frank de Boer was in charge.
He recalled to Ziggo Sports: "It was my wish to leave this summer, but that was not the case.
"There was something, and there was an offer, but it was never so far that a transfer was seriously an option."
Asked if he could leave in January, Zoet added: "If something is beautiful, you should always think about football. But at this point, I'd rather just finish the season."
