The departure of Diogo Leite, a 27-year-old Portuguese centre-back, from Union Berlin has been considered certain for months, with the timing having been previously unclear. A transfer to Lazio Rome in the winter did not proceed at the final stage, and Leite will be available as a free agent in the summer. Borussia Dortmund could potentially act on this situation, as the futures of several of their central defenders, including Nico Schlotterbeck, Emre Can, and Niklas Süle, are reportedly unsettled. Leite joined Union Berlin in July 2023 and has made 16 appearances in the Bundesliga this season. His current market value is €12.00m, according to Transfermarkt.
