The 20-year-old had an impressive breakthrough season establishing himself as a first team player this season.
Tufan also broke into the Turkish national team and scored on his debut against Denmark in September 2014.
Bursaspor are reported to value the young midfielder at €10 million and rejected all offers for their rising star in January.
“Other big European teams have sent scouts to watch Ozan play…AC Milan, Juventus, Chelsea and both Manchester clubs, City and United,” Mehmet Tufan told Spanish newspaper AS.
The 20-year-old midfielder has three goals and nine assists in 41 appearances for Bursaspor this season.
