Bayern are trying to sign Leverkusen defender Tah immediately, but cannot complete his signing before his contract expires at the end of June. With the Club World Cup on the horizon and defensive injuries piling up, the Bundesliga winners want Tah to join in time for the tournament in the USA. However, Sport Bild reports Leverkusen are not willing to let him leave for free just yet and are demanding a transfer fee to release him early.
