There are reports Napoli will again look to Turkey for reinforcements in January, including Fenerbahce midfielder Sebastian Szymanski and Hatayspor talent Fisayo Dele-Bashiru.
The Partenopei have history of finding impressive new players in the Turkish Super Lig, above all defender Kim Min-jae from Fenerbahce.
They are now looking back towards this club for Poland international Szymanski, a 24-year-old creative midfielder who already has two goals in 28 senior caps for his country.
Szymanski only joined Fenerbahce over the summer from Dinamo Monscow for €9.75m after a loan spell in the Netherlands with Feyenoord.
So far this season, he has contributed nine goals and seven assists in 19 appearances.
Another Napoli target is Dele-Bashiru, a 22-year-old midfielder who came up through the Manchester City youth academy and played for Sheffield Wednesday before joining Hatayspor as a free agent in July.
He has four goals and three assists in 11 games this season and his brother Tom plays for Watford.
