The French publication claims that the France Under-19 international is unlikely to win a new contract at Marseille, but he has impressed during his trial with Sunderland and is set to be offered a deal.
The 18-year-old comes from Digne and joined the Marseille youth ranks as a highly-rated prospect.
Predominantly a central midfielder, Erdogan is comfortable in possession and has a strong engine, allowing him to get up and down the pitch and act as a box-to-box player.
Despite impressing enough to earn international recognition with the French youth teams, Marseille are reported to have little intention of offering him a professional contract, allowing Sunderland to step in.
Sam Allardyce has made some key signings for Sunderland since taking charge of the club, but Erdogan is very much one for the future and his arrival could hint at the Englishman staying on long-term.
With Erdogan seemingly set to sign a contract at the Stadium of Light, interestingly Sunderland striker Steven Fletcher is currently on loan at Marseille where a permanent deal may take place this summer.
