His father Juan Ramon Veron said in an interview with Greek sports newspaper Sportime that his son could join Panathinaikos.
He said: “We do not have an official offer in our hands but I am in talks with Panathinaikos’s management and we are making great progress.
“Panathinaikos offered to work with us a few days ago. We had a phone conversation with Panathinaikos’s technical director and we are thinking about the offer very seriously.
“Sebastian and I, we are going to contemplate this offer very carefully and if we decide to move on we will both talk to the club for a possible move.”
Panathinaikos have refused to comment on the negotiations with Veron.
The 32-year-old’s contract expires in June.
