According to British and German press, the transfer fee for the 22-year-old could go up to 40 million euros ($47 million), including 10 million euros in add-ons.

German specialist media Kicker and The Athletic also reported the inclusion of a 60-million-euros buy-back clause in the contract, which Liverpool could activate from summer 2027 to re-sign Quansah.

"We are very happy to be able to sign Jarell Quansah, one of the most promising English central defenders," said Leverkusen managing director of sport Simon Rolfes.

"He made a very impressive contribution to a Liverpool defence full of world-class players. Jarell will give our defence extra dynamism, tempo and strength."

Quansah becomes the most expensive signing in Leverkusen's history, following on from the previous record arrival of midfielder Kerem Demirbay for 32 million euros in 2019.

The 2025 European under-21 champion with England joined Liverpool's academy as a five-year-old, and rose through the ranks before making his first-team debut in 2023.

He went on to appear 58 times for the Merseysiders, winning the League Cup in 2022 and 2024, as well as the Premier League title last season.

After playing second fiddle to first-choice defensive duo Virgil van Dijk and Ibrahima Konate for much of the 2024/25 campaign, Quansah arrives at Leverkusen to replace departed former captain Jonathan Tah at the heart of the Bundesliga club's defence.

"The ambitious targets here were clearly explained to me during the negotiations. It's a great role and challenge for me to be part of the current Leverkusen rebuild," said Quansah.

After creating league history by winning the Bundesliga undefeated in 2024, Leverkusen endured a difficult title defence last term, finishing 13 points adrift of winners Bayern Munich.

Stars of their league-and-cup double from two seasons years ago, Florian Wirtz and Jeremie Frimpong, have recently gone in the opposite direction from Quansah, joining Liverpool from Leverkusen this close-season.
