According to journalist Giannis Chorianopoulos, who first broke the news of Barkas’ move to Glasgow last summer, a loan move when the window re-opens is “possible” though it won’t be back to Barkas’ homeland.
He tweeted: “Barkas was not in Celtic squad v Ross County. Seems, he's running out of time in Celtic Park. On loan in summer transfer window is possible. Greece is NOT an option at the moment #Celtic #CelticFC #Barkas”
This came a day after Chorianopoulos tweeted that Celtic are looking to sign another goalkeeper this summer as they already look set to move on from the ex-AEK Athens star.
Barkas has failed to live up to his reported £5 million transfer fee and twice found himself dropped from the starting XI for extended periods.
