The 23-year-old has been on loan with the Greek side since January.
“It’s been the most fantastic experience,” he told the Daily Mail.
“How many English players have gone abroad to play for a massive club like this? I jumped at the chance.
“I’m really happy with how everything’s gone. I’ve scored six goals and hopefully I can help us win the cup.
“I could be going home with two medals. The last time I won anything was in Sunday League!”
He added: “I’ve had people coming up to me in the street, saying they’d love me to stay.
“I’d be happy to, but we’ll see what happens.
“If I don’t go back, I’ll never forget their fans. I don’t think you’ll see fans like these anywhere in the world.”
