Al Ahli say they are considering an offer for midfielder Humam Tariq, 18, who became the youngest ever Iraq international and already has 15 caps.
Tariq came to prominence last year after an excellent showing in the Under-20 World Cup, where he helped Iraq to the semi-finals and gained his nickname.
That alerted several clubs in Europe to his potential, but Ronny Deila appears to have made the first move.
Tariq racked up 21 goals in 46 appearances for former club Al-Quwa Al-Jawiya, attracting attention from Al Ahli, whom he has yet to make an appearance for.
His agent, Najim Abed Mohamad told Sport 360 that Celtic had noted interest.
“Celtic sent a request to me and Al Ahli,” Mohamad said. “They want to invite him for a trial.”
Al Ahli’s Romanian manager Cosmin Olaroiu said: “We have received a formal offer from Celtic. We travel to a training camp in Germany this month. During that time, we will sit down and assess Humam’s situation and decide whether we will accept the offer from the Scottish club.”
