Last winter, Thomas Kastanaras was loaned from VfB Stuttgart to the then third division team SSV Ulm 1846, and with three goals in 16 appearances, he also contributed to the sparrow's promotion to the second division. However, the 21-year-old striker has not yet made his breakthrough, and he is likely to continue to find it difficult in Stuttgart. Another loan is not possible without a contract extension beyond 2025, a transfer is an option. Besides Ulm, other clubs are also interested - but VfB wants to secure a buy-back option.
