The Greece international said: "It was a good opportunity for us on Wednesday to go first in the table but trust me, there is a lot of twists and turns until the end of the season and both teams will lose points, that's for sure.
"There's still nearly 30 games remaining, it's not possible to win all the games.
"We must forget what happened against Hearts. It's in the past and we are looking forward.
"I don't want to make any excuses, say what was wrong or what was bad, all I want to do is focus on the next game.
"When you lose a game it is not the best feeling but there is always the next day in football and all we can do is focus for the next game against St Mirren away."
