The transfer was not a straight release from Xabi's contract, as Bayer Leverkusen insisted on receiving compensation from Real Madrid.
As a result, Real Madrid paid €15 million to secure Xabi's release, which is significantly higher than the previously reported €5 million.
Interestingly, Xabi's replacement at Bayer Leverkusen, Erik ten Hag, will join the team as a free agent, and his appointment is expected to be confirmed soon.
