Union Berlin has shown interest in signing Sinaly Diomandé from AJ Auxerre. The transfer fee for the Ivorian central defender is expected to be around 4.5 million Euros. This deal could be financially supported by the sale of Leite or Doekhi. However, Union might face competition from FC Everton, who have also expressed interest in the eleven-time Ivorian international. Everton's stronger financial position could pose a challenge for Union Berlin in securing Diomandé's signature.
