Newcastle United officials fear Demba Ba has held talks with Galatasaray.
Social media claims were denied by Toon last week that Ba had agreed to join Gala on a five-year deal.
But a senior source told The Journal that they suspect meetings in Turkey have taken place, and would be unsurprised if he leaves.
Ba's family do not come from money and with the striker's stock so high, it is being viewed as a once-in-a-lifetime opportunity to cast around for lucrative options.
