Celtic manager Martin O'Neill: "I thought there were periods where we played some really fantastic stuff.
"There was also periods where they played fantastic stuff. It was really like a basketball game, particularly in the first half.
"We rode a little bit of luck, they had a great shot in the first minute. Just marginally offside.
"They had a great chance just a moment or two after that, so they started the brighter, and it took us time to get going.
"But when we did, then we scored.
"Great goal by Benjamin Nygren to take a bit of pressure off, give us the lead, and then Camilo Duran's two goals were fantastic.
"But the game is absolutely in the balance yet.
