Newcastle United have a deal in place for Olympique Marseille winger Florian Thauvin.
Newcastle have been pursuing Thauvin for much of the summer and RMC says terms have now been struck.
A source close to negotiations revealed: "This offer is indeed €17 million net and will be paid immediately.
"The proposal is 'irrefusable'."
It's expected that Remy Cabella will move in the opposite direction on-loan as part of the deal.
