PAOK have reportedly handed Greg Taylor a deadline of the end of June to decide his future.
The Celtic left-back is weighing up his options ahead of his current Parkhead deal expiring soon.
Boss Brendan Rodgers has made no secret of the fact he would like to see Taylor remain at the club and battle with Kieran Tierney for a starting spot next season.
However, PAOK have been strongly linked with the 27-year-old as they prepare for their Europa League campaign - and are said to have offered two year contract with the option of a third that will trump his current Celtic salary.
PAOK technical director Christos Karipidis has confirmed the club are waiting on a response from the Scotland cap - and Greek outlet Sport Dog now claim a deadline has been set for a decision.
