"I was just focused on the ball, but I knew that I would score. I'd had that feeling before the game so I'm very happy.
"I've just been focussing on my football, I've been training hard, I knew that my chance would come and it was up to me to take it. I'll keep going and keep working hard."
The Greece international added: 'Other players might worry, but I stay really calm, don't get stressed, play my own game and enjoy it. Whatever happens, I have confidence in myself and I just keep trying."
