RB Leipzig is seeking a replacement for Yan Diomande, who is in advanced negotiations for a transfer to Real Madrid. Bild has identified five potential successors, and Paul Nebel of Mainz 05 is one of the candidates. Nebel, a 23-year-old German attacking player, currently has a contract that is set to expire next year. Because it is reported that he is hesitating to sign an extension with Mainz, RB Leipzig apparently views him as a potential acquisition at a favorable price. His current market value is estimated by Transfermarkt to be €18.00m.
