Jonathan Glao Tah was born on 11 February 1996 in Hamburg, Germany, and developed through Hamburger SV's youth system, making his competitive debut in 2013. After a loan to Fortuna Düsseldorf he joined Bayer Leverkusen in 2015 for around €7.5 million, and over ten seasons he made 291 Bundesliga appearances and became the foundation of the club's defence.
His career peaked in 2023-24, when Leverkusen won their first ever Bundesliga title under Xabi Alonso. He was named to the Bundesliga Team of the Season and reached the UEFA Europa League final. Bayern Munich agreed an early-release deal with Leverkusen — reportedly worth around €800,000 — to bring him in ahead of the 2025 FIFA Club World Cup, and he joined as a free agent in May 2025. In his first Bayern season he won the 2025-26 Bundesliga title and scored important goals in domestic and Champions League fixtures.
For Germany he has earned around 45 caps, played at Euro 2024 and scored his first international goal in March 2026 in a 4-3 win over Switzerland.
Standing 1.95 m and right-footed, Tah is a tall, physical centre-back who combines aerial dominance with positional discipline and clean distribution out of the back — exactly the kind of senior, big-club-ready leader Bayern wanted in their post-Süle, post-De Ligt back line.
