The Scottish champions were beaten by the Kazakhstan side 2-0 in Astana last week and now need to overcome that deficit to force their way into the group stage proper of Europe's premier club competition for a second straight season.
With Celtic needing at least two goals to secure their spot in the Champions League, Greek forward Samaras says is not too perturbed when the goals come, as long as they do.
"An early goal would be perfect but we can´t panic," Samaras told the club's official website. "We have to play our game and move the ball really well and the chances will come.
"I really don't care if the goals come in the first 10 minutes or the last 10 minutes. It is 90 minutes and it´s plenty of time. We have scored many goals at Celtic Park in the past and the main thing is we are clinical with the chances we create.
"Nothing has changed. The way we think and the way we play, our style of football at Celtic Park is the same in domestic games. We have the most possession and try to create some chances. If we concede then we will have to score four goals, but we have done that before at Celtic Park and we can do it again."
