Germany's World Cup Preparations Hit Hard by Lennart Karl's Injury

Germany’s World Cup preparations have been hit hard, and it happened in the cruellest way possible: on the eve of a friendly, in a routine training session, a teenager who had just burst onto the international stage saw his tournament vanish.

Lennart Karl, the 18-year-old forward who had electrified the Bundesliga this season, has been ruled out of the World Cup after tearing a muscle bundle in training, the German Football Federation (DFB) confirmed on Friday.

“Lenny tore a muscle bundle today in the final training session and is ruled out because of this injury. Have a good recovery, we're thinking of you,” the DFB posted on Instagram, the message underlining the shock inside the camp.

Only days ago, Karl was the feel‑good story of Germany’s build-up. A Bayern Munich prospect thriving under Vincent Kompany in a league-winning side, a fresh face who had forced his way into Julian Nagelsmann’s plans with a breakout domestic campaign and fearless attacking play.

Now, his World Cup is over before it began.

From revelation to heartbreak

Nagelsmann had already sounded a warning note in Chicago ahead of Saturday’s friendly against the United States, admitting Karl’s injury “didn't look good” and confirming the youngster had been taken to hospital for a scan. The diagnosis ended any lingering hope.

For Germany, it is not just a name lost from the squad list. Karl had brought a jolt of energy to a side trying to redefine itself. He made his top-flight debut only this season, then surged into Kompany’s title-winning Bayern side and stayed there, one of the revelations of the campaign.

He carried that form onto the international stage. On Sunday, in a 4-0 win over Finland, he started his first match for Germany and marked it with an assist, a performance that hinted at a bigger role once the tournament began.

The momentum has been abruptly cut short.

Ouedraogo called in as replacement

Germany have moved quickly to plug the gap, calling up RB Leipzig midfielder Assan Ouedraogo to replace Karl in the squad.

Ouedraogo brings a different profile, more midfield balance than direct attacking threat, and his inclusion subtly reshapes Nagelsmann’s options. The coach loses a forward who stretches defences and gains a young all-rounder who can help control games.

It is a pragmatic response to a problem that, emotionally, will sting for some time.

Neuer on hold, but still in the plan

Karl’s injury wasn’t the only fitness concern Nagelsmann addressed. The head coach also confirmed that Manuel Neuer will not be ready in time to face the United States, though he remains optimistic about the veteran’s availability for Germany’s opening World Cup match against Curacao on June 14.

Neuer, 40, was a surprise recall in May, almost two years after announcing his international retirement. His return instantly reignited debate about hierarchy, leadership and loyalty within the squad. Nagelsmann, though, made his stance clear.

“At his age, he doesn't need a warm-up phase,” the coach said. “He knows how to handle high-pressure situations. He's on his way to peak fitness. However, we don't want to take any risks tomorrow.”

The message is blunt: Neuer stays central to the plan, but not at the cost of another injury drama on the eve of a major tournament.

A test of depth and resilience

In a single day, Germany have been reminded of the fine line between promise and reality at this level. A teenager who looked ready to light up the World Cup is out. A 40-year-old World Cup winner is being carefully wrapped in cotton wool for the big stage.

Nagelsmann must now show that the depth he has trusted, the blend of emerging talent and hardened champions he has assembled, can absorb a loss as sharp as Karl’s and still carry Germany into this tournament with conviction.

The World Cup will not wait. The question now is whether this setback becomes a defining wound, or just the first test of a squad determined to write a different story.
