TEAMtalk reports that Union Berlin bosses are closely monitoring the situation of Ao Tanaka. The 27-year-old has a market value of 10 million euros, according to transfermarkt.de. Tanaka moved in the summer of 2024 for around four million euros from Fortuna Düsseldorf to England and has a contract with Leeds United until 2028. If a suitable offer is made, the club would be willing to negotiate.

Japanese international Ao Tanaka is of interest to three German clubs, including preliminary interest from Union Berlin. Two other clubs, Schalke and Hannover, are also making preparations for a potential transfer and are expected to increase their efforts if they secure promotion. Leeds United are open to a departure and are considering a sale if a proposal is beneficial, with their decision also depending on which division the club is in next season.
