Transfer interest is building around Borna Sosa, with Mainz understood to be weighing-up a move for the Crystal Palace defender. While there has been no official bid as yet, the club may act swiftly if they decide to pursue the deal before the transfer window slams shut. Fiorentina have not withdrawn their interest and could still influence the outcome. Across the season 25/26, Mainz have let in 26 goals in 15 (1.73 per game), roughly in line with the Bundesliga average. Borna Sosa would be expected to give them some extra stability and depth for the tougher stretches of the season. Crystal Palace have also been linked with Kevin Danois, Joao Gomes and Ilan Kebbal while Mainz are reportedly monitoring Silas Wamangituka, Kodai Sano and Phillip Tietz.
