Ghana international Daniel Opare is expected to make his loan stay at Besiktas permanent according to Sporx.
The Black Eagles loaned Opare from Portuguese giants Porto in January until the end of the season with a buyout clause option.
Opare has returned to first team training with Besiktas following an injury that ruled him out of the goalless draw against Basaksehir on Monday.
The 24-year-old has become a fan favourite despite only joining in January. The young full-back was a star performer in Besiktas victory over Liverpool in Europa League Round of 32.
The Ghana international has 17 international caps for the Black Stars
