AEK Athens striker Rafik Djebbour is training with Celtic, according to the player's agent.
The Algeria international has suffered a bust-up with AEK boss Dusan Bajevic after taking a holiday without permission, and he is no longer wanted by the Greek outfit.
Djebbour's representative, Farid Ayad, claims his client is using his exile as an opportunity to try and impress Celtic boss Tony Mowbray.
Ayad has stated that the 24-year-old is training with the Bhoys before Algeria's World Cup qualifier against Rwanda on 11th October.
Ayad said in SportDay: "Rafik has been in Glasgow since Saturday and is training with Celtic. He will be there until Sunday.
"On Monday he will leave because he has to join the national team for the game with Rwanda.
"After this game with his national team he is obliged to return to AEK, but I can assure you he doesn't want to."
Ayad has also revealed that discussions have taken place regarding Djebbour's possible exit from AEK, but SPL side Celtic's stance remains uncertain.
He added: "After my talks with the Celtic people I asked for a price from AEK. I don't know if Celtic are going to make an official offer.
"The next few days will be critical for the future of my client."
