The midfielder said there were several aspects to making a decision about a potential switch, but insisted he was yet to take Spanish language classes.
"My feelings about a club have to be positive. I don't mean that it's only important to feel wanted, I also need to fit in to the style of play," Van de Beek told Helden.
"And of course, I would need to know how much playing time I would be given."
He added: "It's always nice to play in the sun, but I haven't started taking Spanish classes yet."
Van de Beek had scored 10 goals in 37 games for Ajax this season before the campaign was suspended due to the coronavirus pandemic.
