Kasper Schmeichel knew he was in trouble when he shipped four goals at home to Stuttgart - and was at fault for two of them. The Denmark veteran, 39, endured one of the toughest nights of his career as he was jeered by a section of peeved-off fans for his calamitous role in the Europa League collapse.
Everyone inside the stadium could see that Schmeichel - one of the greatest keepers of his generation - was no longer capable of playing for Celtic. His costly mistakes against the Germans weren't a one-off; clangers had crept into his game since his blunder in the Treble-busting Scottish Cup Final defeat to Aberdeen in May 2025.
After that horror Euro night in February, Schmeichel would play just one more game - a 2-1 defeat to Hibs days later - before being told his career was over due to an underlying shoulder injury.
Reflecting on retirement
In an interview with FourFourTwo, Schmeichel reflected: "I'm just trying to get used to it. It's strange because it's been out of my control. The surgeon said my shoulder wasn't going to be fixed to play at the level I wanted to play at. The decision was taken for me. It's definitely not how I wanted it, my career's finished, but I've had some time to reflect."
"I've been lucky enough to experience a lot of things, play over 900 games, be part of the teams I've been part of, win the trophies I have."
"It was a specific injury that happened in the Stuttgart game. It was actually fine and it was right at the end of that I felt I needed to get it checked out. It was pretty damaged. The conversation with the doctors became less about actually playing again, but about quality of life. It was really strange in the sense that I was still under contract at Celtic, in and around the team."
"I played 39 matches during the season. We were going for a Double, which we ended up getting. I was still very much trying to be part of that, even though I couldn't be."
Fond memories of Celtic
Despite falling victim to an extraordinary backlash from Hoops supporters in his final months at the club, Schmeichel has nothing but fond memories of his two years in Glasgow and says Celtic will always have a special place in his heart.
He said: "I look back on my time at Celtic with nothing but great memories. It's a club that got under my skin very quickly. It's just a special club, the whole intensity of it, how much it means to people, and the responsibility you feel being a Celtic player."
"When you live in Glasgow, it's all anyone talks about. There are Celtic fans everywhere around the world. You have to win every single game and not just win it, win it well. I love that."
"It's everything about the place, driving up to this monumental stadium, you see the Jock Stein statue. Then you walk in, all the pictures, all the history of the club everywhere."
"You go in the dressing room and it's got a lovely blend of refurbs, but still a lot of old school stuff there. You walk through the tunnel and there are plaques and names, then being on the pitch and the noise. It's deafening."
"It's just the passion. All of it grips you. In terms of actual intensity, I'd struggle to think of anywhere louder."
"One of my favourite things was always the Champions League games, when the anthem started, then the massive roar. When we lined up, I used to love looking at the opposition, to see their faces. They were like, 'Wow, this is incredible.'"
"Any opposition player you may have known from the national team or somewhere else, you were talking after the game and they were all like, 'This is immense.'"
One regret and future plans
While Schmeichel wasn't given the grand farewell like predecessor Joe Hart, he did hang up the gloves with another two winners' medals as Martin O'Neill dragged Celts back from the brink to mastermind an incredible Double. But there will always be one slight regret.
He said: "Every footballer dreams that he'll bow out on the pitch. That's what I would have liked - to be able to say thank you, to show my appreciation for the support and love I received through the years. But it was more important to finish the year with the trophy, and we did finish with you. That, for me, was the most satisfying part through a lot of adversity. That we got over the line in the end was massive."
Schmeichel spent the summer working as a World Cup pundit for Fox Sports but isn't sure what the future holds.
He added: "The honest answer is, for the first time in my life, I actually don't know. That can be really scary and also really exciting. I flip between things. Football will without question be at the heart of it. I'm going to try a lot of things. I'm starting a director of football course."
Might he test himself in the dugout? "I wouldn't rule it out at all", he said. "I love being out there. I've really enjoyed some of the coaching and punditry. I'd love to run a club. I'd love to own a club, but that's going to be difficult."
