Ajax sporting director Overmars was also asked in-demand star Donny van de Beek.
"No idea, at least that hasn't made it onto my plate yet," Overmars said when quizzed on Barca's rumoured interest.
Overmars added: "It's pretty quiet. I certainly think the market has yet to get going. That makes sense: the Champions League has only just ended, so that will start soon.
"There is always interest for some players. A few players look good, one player has fairly serious interest. Who that is? That will show itself in the coming weeks."
