Niklas Süle's Weight Struggles: The Hidden Battle at Bayern Munich
Niklas Süle had barely finished saying the word “retirement” before the tributes to his Bayern Munich years began to roll in. Titles, tackles, that improbable turn of pace for such a big frame — the usual checklist.
But on the “Spielmacher” podcast, the defender pulled back the curtain on something far more personal. Not a trophy, not a goal. A scale.
The weigh-in game at Bayern
“Jupp Heynckes was a tremendous mentor to me. I played under him, but he also addressed the issue of weight,” Süle recalled, as captured by @iMiaSanMia. At Bayern, Thursdays meant weigh-ins. For Süle, they also meant something close to a weekly ritual of self-punishment.
“I didn’t eat anything all Wednesday, I fasted the whole day. And every evening at home, I went to the sauna – wearing a raincoat,” he said.
The image is jarring. A modern Bundesliga star, at one of the world’s most professional clubs, cutting weight like a fighter before a title bout. No food. Sauna sessions in a raincoat. All to hit a number on a Thursday.
“The next day, I weighed two and a half kilos less. That’s extreme,” Süle admitted. The sauna sat in the basement of his home. After the full-day fast and the sweat sessions, even the stairs became an ordeal.
“After a day without food and in the sauna wearing a raincoat, I had to go up three flights of stairs to our bedroom. I opened the window, leaned out, and breathed for ten minutes because I thought I was going to faint.”
The pressure finally told on the scale, at least. The number dropped. The player didn’t.
Heynckes’ verdict – and Süle’s reality
The story doesn’t end in the basement. It ends on the pitch, where judgments are made and careers are shaped.
“Then I played at the weekend, we won, and Heynckes said to me: ‘See? You played much better now.’ But the reality is that my weight was exactly the same as before.”
There it is. The punchline, and the problem.
Süle was essentially doing a boxer’s or MMA fighter’s weight cut every week. Shedding water, not fat. By the time the ball rolled on the weekend, his body had already returned to its usual playing weight. The number that had sparked all the drama on Thursday meant nothing by Saturday.
The method was wild. It was also dangerous. And yet it grew out of a truth that followed Süle throughout his career: his weight, his fitness, his frame were always under the microscope.
A defender built for dominance
Strip away the noise and the numbers, and the footballer remains. At his peak, Süle was a force.
On the backline, he offered a rare combination: height, strength, and genuine speed. Not “for a big man” speed. Real, closing-sprint speed that allowed him to recover, to chase, to smother attacks that looked lost causes for most centre-backs of his size.
When asked to play at right-back, he became something almost unique — perhaps the most physically imposing full-back of his generation. A hulking presence out wide, yet still mobile enough to hold his own against wingers who built their careers on acceleration and one-v-one duels.
In his natural role at centre-back, he was a clearing machine. He bullied big strikers, won his battles in the air, and still had the legs to frustrate forwards with elite pace. At times, he looked like the prototype for the modern defender: strong enough for the old game, quick enough for the new one.
And yet, always, the whisper: his fitness. His weight. The sense that something about his physical condition needed managing, measuring, discussing.
The question that hangs over his career
Some players can carry extra kilos and still dominate. The game is full of examples of footballers whose talent and understanding of space made a mockery of body-fat percentages and fitness charts.
Maybe Süle belonged in that category. Maybe his frame, his natural build, was simply different — and the obsession with a number on a scale did more harm than good.
Or maybe, with a different approach to health and conditioning, he might have pushed his career to an even higher level. Fewer battles with the scales, more energy for the battles in the box.
That tension sits at the heart of his story: a defender who, at his best, looked special, yet lived under the constant shadow of scrutiny over his body. The trophies and performances will always be part of his legacy. So will the image of a top-level international defender, starving himself on a Wednesday and sweating in a basement sauna in a raincoat, just to make a Thursday weigh-in.
For all the talk about tactics and systems, Süle’s revelation is a stark reminder of something else: in elite football, the most demanding opponent isn’t always the striker in front of you. Sometimes, it’s the number on the scale.
