Back in the Championship after a brief absence from the second tier, Birmingham City took League One by storm last season and should immediately have one eye on a potential playoff push in the 2025-26 campaign.
The 2010-11 EFL Cup winners started off quickly, with two players whose loan deals from the 2024-25 season were converted into permanent switches.
Taylor Gardner-Hickman and Alfons Sampsted penned long-term deals at St Andrew's, while centre-back Phil Neumann arrived on a free transfer from German outfit Hannover 96.
Birmingham also banked £3m by selling 18-year-old Romelle Donovan to Brentford, and at the other end of the experience scale, veteran striker Lukas Jutkiewicz - double Donovan's age at 36 - hung up his boots. Since, then, Blues have secured several more eye-catching recruits.
Here, Sports Mole tracks all of Birmingham's summer transfer business, keeping you up to date with all of the club's incomings and outgoings.
