The French side put in an nervous display at home against the Greek side, but managed to secure 2-1 win, seeing them through to the quarter-finals of the Champions LEague 3-1 on aggregate.
“We made it hard for ourselves in the second half,” Gourcuff told Canal Plus.
“But we had a fantastic first half, we should actually have been 2-0 or 3-0 up at the break.”
