Newcastle are hopeful of completing a deal for Eibar defender Florian Lejeune, who has an £8.7million release clause in his contract, within days.
The Magpies have been locked in negotiations with the La Liga outfit for some time over the 26-year-old Frenchman.
However, sources on Tyneside have indicated that they are close to reaching an agreement which would give manager Rafael Benitez his first summer signing.
Former Auxerre and Villarreal central defender Lejeune signed for Manchester City in July 2015, but was loaned straight out to Spanish second division side Girona.
