The former Olympiakos man is an integral part of the Greek side having helped his country go on a fine run during their qualifying campaign and feels the side hold no fear despite being part of a strong group which contains the Spain, Russia and hosts Portugal.
Giannakopoulos 29, was a scorer for the Greeks in their 1-0 qualifying win against the Spanish team which took them on an unbeaten run leading up to the summer and the midfielder suggests that the high confidence within the camp will be an advantage.
"It is a tough group but maybe we have a chance. Nobody expected us to win in Spain but we did. At the moment losing is not something we are familiar with and that is important."
