Dutch club PSV Eindhoven, who had previously denied any interest in Vennegoor of Hesselink, will consider to make a move for the out-of-contract player.
The Eredivisie club’s technical director Adrie van Kraaij had described speculation about the 30 year-old as “nonsense”.
But after being informed of Celtic’s decision to let the player go, Van Kraaij admitted the prospect of a free transfer could yet entice the club to make a move.
“Is he really allowed to leave Celtic as a free agent? That’s news to me,” Van Kraaij told Dutch newspaper Spits.
“Those stories that we were interested earlier on were nonsense. But now I will start talks internally, like we always do.”
“Apart from that I won’t give any comments.”
Vennegoor of Hesselink’s contract at the Hoops expired earlier this week and new boss Tony Mowbray indicated yesterday he was happy to let the frontman leave Celtic Park.
He said: “I have had no contact with Jan. Jan is out of contract – he is free to seek other employment and I’m pretty sure that’s what he will be doing at the moment.”
