Kieran Tierney believes that Celtic showed their mettle last night as they rebounded from the setback of losing a late goal to pick themselves up and get the win they needed. And the Scotland full-back questioned whether the Parkhead side would have folded under similar circumstances earlier in the season.

"The biggest plus from the game was the way we reacted to the Leipzig equaliser," he said.

"In the past, we have crumbled when we conceded a goal. This time, we went forward, put pressure on them and got the winner.

"It was great play from Scott Sinclair and Ryan Christie, and a great finish from Odsonne. That was a big goal and a big win for us. It was a big step forward.

"We always say that we will try to learn from mistakes and we did that.

"It;s not in easy in Europe against anyone.

"That felt like a Champions League night against one of the biggest and best sides in Germany.

"It was a great night for us all but we need to now focus on the next few games." Tierney netted the opening goal and admitted that it felt sweeter than the strike he netted against Manchester City in the Champions League two years ago.

"Jamesie cut a lovely ball back and it came all the way through to me," he said. "All I was thinking was, 'Touch and shoot'.

"I hit it as hard as I could and hoped for the best. Luckily for me, it went in - even though the keeper got a toouch.

"To score at that end was amazing. Everyone knew where I was running. It was a brilliant way to celebrate but you can't get too carried away as the game is back on.

"I scored at the same end against Man City but we didn't win that night, so I was gutted. To get a goal in a win like that makes it even sweeter." The result keeps Celtic fighting for Europa League qualification into the knock-out stages."
