Real Sociedad are reportedly on the verge of signing Turkish starlet Yusuf Yazici.
Marca cites Turkish sources, which claim La Real will pay €13m for Yusuf and entitle Trabzonspor to 25 percent of a future sale.
The 21-year-old, who was named by UEFA as one of its 50 young players to watch in 2018, is expected in San Sebastian next week to put pen to paper with Los Txuriurdin.
Primarily an attacking midfielder but also capable of playing on the right, Yusuf scored 10 goals at club level last season and has nine caps for his country.
La Real have history of Turkish players in their ranks, Tayfun Korkut and Nihat Kaveci helping them almost win La Liga in 2003.
