Ronny Deila’s men go into the second leg of their second qualifying round tie against FC Stjarnan with a 2-0 advantage from the first leg at Celtic Park last Wednesday.
Gordon is wary of the threat posed by the Icelandic side, despite not having to deal with a single shot on target during the 90 minutes in Glasgow.
“They have shown they can create chances and we have to approach the game in the right manner and make sure we defend well first and foremost and then look to score goals,” he said.
“They had a couple of chances, especially in the second half. I remember one that was quite close, a shot from the edge of the box, and if they had nicked a goal there it could have been an even more difficult task.”
The Celtic No 1 knows all too well the feeling of being knocked out this competition in the qualifying stages. He was part of the team that failed to reach the group stages after being beaten 2-1 on aggregate by NK Maribor last year.
And the Scotland international insists he has not thought about their potential opponents in the next round, refusing to believe Wednesday’s match in Iceland is a mere formality.
“We have to try and make sure we win this game first and we can think about that as and when if that happens,” said Gordon, whose side face a lengthy trip to Qarabag or Azerbaijan or Montenegro side Rudar Pljevlja if they prevail.
“We are going to this game and we will look to defend very well, be nice and compact as a team and then try and win the game of football as we would do regardless of who we are playing or where we are playing,” he said. “We will look to try and win the game and then we can see what happens after that.”
Wednesday’s second leg will be played on the artificial pitch at Stjörnuvöllur but Gordon says the surface will prove no disadvantage to the Scottish champions.
He said: “There isn’t much difference. Grass surfaces can vary in terms of bounce and the ball can skid through to the goalkeeper anyway.
“Every pitch is slightly different and you have to suss that out during the warm-up. We’ve had a look at it, trained on it and we’ll get used to it and adjust accordingly.”
