The former Portugal international will have a medical with the Super Lig club on Saturday and is expected to sign a deal worth around £2m a year.
Having already touched down on Turkish soil, Bosingwa was greeted at the airport by a very familiar face.

Former Chelsea team-mate Florent Malouda, who recently joined the seven-time Turkish title winners, was there to welcome his old friend to his new club.
The pair spent four years together at Stamford Bridge before Bosingwa switched to QPR last summer.
However, the 30-year-old right back endured a miserable time at Loftus Road and will be glad to link up with his old pal again at the Hüseyin Avni Aker Stadium.
