Mats Hummels is being closely considered by Bayer Leverkusen as a potential replacement for Jonathan Tah, who is possibly leaving for Bayern Munich. However, there is internal disagreement within Leverkusen about this transfer.

Bayer Leverkusen's involvement has further complicated the situation for Mats Hummels, causing him to delay his decision and keep Beşiktaş waiting.

Mats Hummels is one of the most sought-after free agents, even targeted by top Italian teams such as Roma, Milan, Napoli, and Como. Despite turning 36 in December, he had an excellent season with Borussia Dortmund, leading the club to the Champions League final. He officially left the club yesterday at the end of his contract. Hummels is not looking to retire and seeks a new challenge. Bayer Leverkusen, under Xabi Alonso, could offer him a serious project.
