Celtic are interested in Trabzonspor forward Caleb Ekuban according to Fanatik.
Per the source, the Scottish giants are prepared to offer €5m for the Trabzonspor star.
The Black Sea based outfit want to keep hold of Ekuban but will consider their star man leaving if Celtic increase their offer to €7m.
Trabzonspor signed the 25-year-old for just €1m from Leeds last season.
The Ghana international had an impressive season scoring 10 goals and providing 11 assists in 34 appearances for Trabzonspor.
The Claret-Blues finished the Super Lig as runners-up and lifted the Turkish Cup.
Despite finishing as runners-up Trabzonspor will not compete in the Champions League next season due to receiving a ban from UEFA over breaching their Financial Fair Play agreement.
As a result the club will have to sell players in order to make additional signings and meet their FFP terms in order to avoid further punishment.
Ekuban has another two-years remaining on his Trabzonspor contract.
The Ghana international was born in Italy and has EU citizenship and has previously played for Chievo, FK Partizani and Leeds United.
