Quotes from AEK fans
One said: "It's a shame we lost him, but we managed to keep him for a long time"
Another added: "Good luck Vasilis, the best to you and our friends from Glasgow!"
A fan said: "Good luck, success and health. The top Greek goalkeeper will try his luck. Well done. Thank you for everything."
Another added: "I wish you a Premier League move Vasilis in a couple of years!"
A Celtic fan also wanted to find out what kind of player the Hoops have at their disposal and the responses from AEK fans were overwhelmingly positive.
One said: "Yeah he is really good...he is better than the last goalkeeper you had."
Another replied: "He is the best goalkeeper playing in Greece."
One added: "If he was playing at a more advanced league than Greece, Celtic could never get the transfer with this money. Also even AEK would not agree with the transfer but he wanted to do it. Celtic really got a bargain there. You will see on the pitch."
