The Turkish intentional is expected to have his visa in time for the senior team’s trip this week.
As reported by Turkish-football.com’s Emre Sarıgül writing for the Guardian on Friday Ünal completed a medical before officially signing for the Citizens on Monday on a four-year deal.
Ünal became the first Turkish player to join City and the youngest player from the Süper Lig to make a Premier League move.
The 18-year-old striker holds the record for being the youngest player to ever score in the Süper Lig when he netted against Galatasaray in 2013.
The Turkish international already has seven first team goals for Bursaspor and one senior international cap.
The young striker scored once in 197 minutes of first team football last season and also provided two assists in the Europa League qualification stages.
