Lennart Karl

Lennart Karl returned to training with the ball at Bayern Munich's Säbener Straße complex as he recovered from his thigh injury. The club's pre-season began on 20 July, and he said he would not rush his recovery. He was monitored closely by doctors and athletic trainers.

Lennart Karl was ruled out of the 2026 FIFA World Cup after suffering an injury in training with the German squad in Chicago. Medical examinations diagnosed torn muscle fibres in the front of his left thigh. Coach Julian Nagelsmann had included the 18-year-old in the final 26-man squad before he was replaced by RB Leipzig's Assan Ouédraogo.

Bayern Munich announced that Lennart Karl would be sidelined for the foreseeable future after a muscle fibre tear in the back of his right thigh. He missed the club's match against St. Pauli as a result. At that point he had five Bundesliga goals and four assists in 24 appearances in the 2025/26 season.

Lennart Karl scored in Bayern Munich's 3-1 Champions League win over Sporting Lisbon, becoming the youngest player to score in three consecutive Champions League matches. He netted after Serge Gnabry had equalised and was named UEFA Player of the Match. His goals came in his first four appearances in the competition.

Lennart Karl became the youngest Bayern Munich player to record both a goal and an assist in a single Bundesliga match during a 6–2 victory over SC Freiburg on 22 November 2025. The 17-year-old attacking midfielder scored and provided an assist, cementing his status as one of Germany's most promising young talents.

Lennart Karl made history as Bayern Munich's youngest-ever Champions League goalscorer after scoring against Club Brugge in October 2025. The feat highlighted his rapid rise from the youth academy to the first team, where he has already contributed significantly in both the Bundesliga and Champions League.
