ELFSBORG left Celtic Park last night following their 1-0 defeat to the Hoops believing that they can turn their Champions League third qualifier around in Sweden next week.
IT was a tough evening for Neil Lennon's side against the well-organised visitors, but Kris Commons' second-half header gave the Scottish champions a narrow advantage to take to Boras for the second leg.
It was not a vintage performance from the Hoops who huffed and puffed for long spells against the organised and at times robust Swedes.
The Celtic boss said: "I am delighted with the performance and the result.
"They made it difficult for us to break them down but it was not frustrating, it was understandable.
"We weren't at our best but that was always going to be the case, there is still a bit of rust there. We still have a lot to do in the tie but we are confident.
"The crucial thing is the clean sheet. That is important. If we score over there Elfsborg have got to have three. The tie is probably in the balance but we are confident we can go there and get a result.
"The Astroturf might change things with the way I pick my team. But I was pleased with the result. I would have taken 1-0 before the game."
Elfsborg's English forward, James Keene, insisted the Swedish champions have a "great chance" of overturning the deficit.
The former Portsmouth player said: "We are going into the game at home with confidence.
"We are pretty happy with 1-0. We played pretty well. It is going to be a different game when they come to our place.
"I think we have a great chance, it is definitely not over."
Commons, though, was bullish in his belief that Celtic will make it through to the play-offs.
He said: "It could be a vital goal in the grand scheme of things but I do think we can score in Sweden. Fraser (Forster) could have stayed in the changing-rooms. I don't think the ball touched his gloves. We are more than confident about going on the road and getting goals."
