The 28-year old Greek international has been linked with homeland club PAOK but he insists he is very happy with the Scottish champions although he did hint that a future shift to the Greek Super League may one day occur.
"Since last year, things are going very nicely with Celtic," he said.
"Maybe it has helped as we've done so well in the Champions League, but I have just kept trying to do the same thing on the park.
"There was also no contact from PAOK for me to go back to Greece. Anyway, the only club I would join there is OFI Crete because that's where I came from and I grew up there with my father. I'm a bit of a football romantic!"
