It was confirmed on Derby County's published retained list that Callum Elder was one of four senior players being released, making him a free agent. The 31-year-old Australian international left-back also holds Scottish nationality. His final months at Pride Park were affected by injury. The defender has been capped three times by Australia. Clubs in League One looking for success, such as Sheffield Wednesday, will likely be interested in the defender, especially as the Owls are expected to concentrate on free transfers for their squad rebuild. It is also considered a possibility that Elder could remain in the Championship, with interest in him expected to grow following the confirmation of his contract situation. According to Transfermarkt, his current market value is €400k.
