Ajax have emerged as a possible destination for Suarez, who spent four years playing for the Eredivisie champions before joining Liverpool in 2011.
Amid speculation Ajax are in talks to bring Suarez back to Amsterdam, Overmars addressed the rumours.
"Let me put it this way: the chance that he will come is quite small," Overmars told Ziggo Sport as Ajax defeated Hertha Berlin 1-0 in Tuesday's friendly.
"That's a straight answer, I think. Whether there has been any contact with him? We have that with several ex-Ajax players. That is logical, you also have to maintain that."
Suarez, who won the Eredivisie and KNVB Cup during his time at Ajax, has celebrated four LaLiga titles and the Champions League among other honours since moving to Barca in 2014.
