Besiktas have agreed a €3m deal with Norwich City for striker Nelson Oliveira in January.
According to the Star, the two clubs have agreed a fee for Oliveira and he will join the Turkish outfit on a permanent deal in the next transfer window.
The Portuguese international has been excluded from the first-team by Daniel Farke this summer after he handed in a transfer request.
Besiktas were previously thought to be interested in a loan move for Oliviera, with the deal now appearing to be permanent.
The forward scored 23 goals in two seasons for Norwich, including 15 in 31 games in his first campaign.
He was not able to seal a move away before the start of the season, but now looks set to get his dream move in January to Besiktas.
They are not the only Turkish side thought to be interested in a Norwich striker, with Galatasaray reportedly scouting Teemu Pukki – who has scored 12 goals this season.
