CELTIC have had a €5 million bid for Ghanaian forward Caleb Ekuban rejected by Trabzonspor, according to reports in Turkey.

Sport news website fanatik.com.tr say that the Parkhead club have seen their initial approach rebuffed, with the Turkish Super League side holding out for a fee of around €7 million.

The versatile attacker can play as a striker or as a winger on either flank, with Ekuban scoring 10 goals and registering 11 assists in 34 appearances in all competitions last season.

The 26-year-old was on the books at Leeds United for the 2017/18 season before joining Trabzonspor on loan the following campaign.

That deal was then made permanent last summer for a fee of €1m after Ekuban sufficiently impressed the coaching staff at the club.

Neil Lennon has already bolstered his attacking options for the new season after signing Albien Ajeti from West Ham, while Vakoun Issouf Bayo has been shipped out to Toulouse on loan.
