Bruno Guimaraes' contract at Newcastle United is understood to carry a buyout clause.
AS says the Brazil midfielder's deal includes a 115m option.
Guimaraes has been linked with PSG this month, while he's also on the radar of Real Madrid and Barcelona.
For their part, Newcastle are working on convincing Guimaraes to agree terms on a new deal.
But there are doubts about Guimaraes' situation given Newcastle's Financial Fair Play concerns.
