Derby County summer transfers and net spend: Every confirmed signing and sale for John Eustace's side in 2026 window

Derby County finished the 2025–26 Championship campaign in eighth place with 69 points, narrowly missing out on the promotion play-offs.

Despite remaining in the top-six picture for much of the spring, a final-day 2-1 defeat to Sheffield United ultimately allowed Hull City to clinch the final play-off spot, leaving John Eustace’s side short.

However, it was a massive progress for the Rams who were involved in a relegation battle the season before, and now they will hope to build on that by adding more quality ahead of the next campaign.

Here, Sports Mole rounds up all of Derby County's confirmed ins and outs during the 2026 summer transfer window, as well as looking at their net spend and latest transfer rumours.
