Craig Gordon tells Celtic to keep their eyes on Stjarnan as they look to progress in the Champions League

The Scotland goalkeeper wants his teammates to focus on beating the Icelandic champions before worrying about their next Champions League opposition.

Celtic goalkeeper Craig Gordon has urged the Scottish champions to treat their Champions League qualifying match against FC Stjarnan with caution to avoid letting their opponents back in the tie, an interview on the club's website revealed.

The Bhoys are taking a 2-0 lead to Iceland for the second leg of their qualifying bout against Stjarnan, a decent advantage but one that would be dangerous to rely on especially considering Celtic's opponents are at home.

Ronny Deila's side were by far the more dominant side at Celtic Park, registering 22 shots to Stjarnan's 2, but 32-year-old Scotland international Gordon has made it clear that the side have to ensure they approach the game at hand first rather than letting their minds wander to who they may be facing in the next round.

“We have to try and make sure we win this game first and we can think about that as and when if that happens,” Gordon is quoted as saying by the Bhoys' site.

“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. We will look to try and win the game and then we can see what happens after that.

“They had a couple of chances [in the first leg], especially in the second half,” he added. “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.

“They've showed 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.”

The Glasgow club could have had a healthier aggregate score to enter into tonight's match if striker Leigh Griffiths had converted a penalty in the last 12 minutes, only for Gordon's opposite number Gunnar Neilsen to make a stop that may have given the Icelanders a boost ahead of the return leg.

Celtic of course remain heavy favourites to beat the Icelandic champions, and it would be a catastrophic collapse were they to exit the Champions League to the minnows, but it is smart advice from Gordon to ensure the club remain professional in their focus.
