Speaking to SDNA, Calathes acknowledged that the Greens gave a decent display defensively against Olympiakos, which helped them to earn a well-deserved victory.

“In the first half we did not play that well, but I think for the rest of the game our defending was great and we scored some crucial shots as well. Our overall performance was very good,” Calathes told SDNA.

Despite the second win on the trot against the bitter rivals Olympiakos, Calathes do not get complacent.

“It's very early on into the season. We managed to turn around a 15-points difference, however we must keep improving,” Calathes added.
