'You never want an emotional surgeon': Celtic's safest hands on what keeps them level
With 20 minutes of normal time remaining against RB Leipzig, Kasper Schmeichel turned a wicked Christoph Baumgartner volley round his left-hand post to keep his side a goal in front.
In the days preceding Celtic's most recent European triumph, Baumgartner declared he'd long dreamt of playing in such an iconic and historic arena, and couldn't wait to soak up the electric atmosphere on matchday four of the UEFA Champions League.
After three straight losses in the competition, the pressure sat firmly on the shoulders of Leipzig heading in – currently second in the German Bundesliga, with the best defensive record in the league – while Brendan Rodgers and his players prepared for a tough night under the lights at Parkhead.
It was Baumgartner who fired his side in front after 23 minutes, but it was Nicolas Kuhn and Reo Hatate who helped the home side triumph 3-1 in what was surely Celtic's most complete European performance for well over a decade.
Man of the Match Kuhn deservedly snatched the headlines, but Hatate was more than deserving of his goal, having dazzled with impeccable vision, an array of cultured, pin-point passes, and tactical discipline worthy of European football's most prestigious stage.
And Schmeichel arguably had the best seat in the house to take it all in. "I think the key to these kinds of games is our one and two touch play," he said. "To be able to play simple, to be able to find space, to be able to have the right weight on the ball.
"I think when you play against a team like Leipzig, pressing the way they do, the second you hold onto the ball for more than one or two touches, then they're on you. I think Reo has shown some incredible skill and some great vision. The great thing was, and the reason we had success, was because he wasn't the only one."
One stray pass aside, another standout performance against RB Leipzig was delivered by Auston Trusty.
Signed on transfer deadline day this summer, the American has gone from strength to strength in recent weeks, replacing Liam Scales in the manager's starting line-up and mirroring the same courageous, attacking-minded stature best portrayed by countryman Cameron Carter-Vickers.
Always determined to play through the lines in support of his front-facing colleagues, the 26-year-old is still growing into his role in the heart of his side's defence, but it is likewise growing in confidence with every game under his belt.
Schmeichel added: "There's a lot of clarity in the system that we play, the way that we want to play and the options that you have available when you're on the ball. I think the most important thing in any game is the passer has options, but it's how the options are received.
"You can, as a passer, even as a goalkeeper, if you pass it to someone, it's only a good pass if they receive it correctly.
"When you're in a system the way that we play, then there are so many options and you've got good technical players who are able to take the ball in difficult situations. You keep it to one-two touch, that's really, really important, particularly against teams like Leipzig, because they're going to get close to you.
"The second you can get them close to you and play the ball, then you're going to create spaces elsewhere. When you're playing in a system that's full of clarity like that, then it makes football a lot more enjoyable."

So too does giving the fans something to cheer about – and overcoming one of Germany's best with succinct, fast and aggressive football is a sure-fire way to get bums off seats.
Celtic's embarrassing result in Dortmund was all but forgotten as Depeche Mode's Just Can't Get Enough and Bobby McFerrin's Don't Worry Be Happy rang out from the stands on Tuesday night, with a place in the competition's last 16 play-off now well within reach.
With seven points on the board and four games remaining, 10 points should be enough to do so, while 16 would almost certainly snag a place in the league-phase's top eight – granting automatic qualification in turn.
Schmeichel played a pivotal role in helping Leicester reach the quarter-finals of the Champions League back in 2017, but dismisses any parallels between what the English Premier League outfit achieved then and what Celtic are aiming to do now.
"[Tuesday] was a great experience," Schmeichel said. "On the pitch, we can hear - well, we can't hear each other sometimes - but you can definitely hear the crowd. It makes a massive difference. Talking to opposition players when they come to Celtic Park, it's not just us that notices it, they notice it.
"So it makes a huge difference to the team and to the game, I think.
"[But] It's the next game. There's no looking beyond that. If you just take one little percentage off this level, you're going to get punished. So it's the next game. And no one in here, in this building is going to get carried away with thinking, we're going to do this, we're going to do that.
"No, you're not going to find anyone proclaiming that. We're going to focus on the next game. Next game is Kilmarnock and then we take it from there."
Kilmarnock will indeed pose a different challenge as Celtic eye the perfect week, following last Saturday's 6-0 League Cup semi-final win over Aberdeen and Tuesday night's European exploits.
After that it's another international break, before Celtic embark on an especially busy fixture schedule.
Win, lose or draw, however, Schmeichel continues to play by his self-proclaimed 'midnight rule', wherein he celebrates or commiserates any result until midnight, before then moving onto the next.
He added: "When you're younger, you're trying to make your way in the game. You're trying to create a name for yourself in the game. You get very caught up in your feelings and your emotions sometimes, and you learn how to control them more.
"I think that's a big advantage when you learn to control those emotions, because if you're going into surgery, you're not going to want an emotional surgeon. You're going to want someone who's clean and clinical. That's what we have to be when we get on the pitch. We have to be clean and clinical.
"When we hopefully win, then that's when we get to feel. If we lose, then we have to feel that. Then you have to cut that off and you have to move on."
