According to sources who spoke to Football Insider, Championship clubs Portsmouth and Lincoln City are both interested in signing Stockport County's English winger, Jack Diamond. The two clubs are seeking to sign the 26-year-old for a reduced price, as he is about to enter the final 12 months of his contract. In January, Stockport wanted a fee of more than £1 million for Diamond. However, sources have now indicated that clubs have been alerted to a drop in his asking price. Both Portsmouth and Lincoln admire the former Sunderland player, and Lincoln previously had him on loan during the 2022-23 campaign. A transfer this summer is considered a possibility because the opportunity to sign him for a reduced fee has resulted in several clubs monitoring him. During the 2025/2026 League One season, Diamond made 45 appearances, scored 6 goals, and provided 7 assists. His current market value on Transfermarkt is €700k.
