Following lengthy negotiations and final medical checks, Eiran Joe Cashin has completed a transfer to Derby from Brighton. The defender is now fully registered and eligible for selection for his new team. It's a statement signing for Derby, who have moved quickly to finalise the deal ahead of the close of the window, with fans salivating at the thought of seeing their new signing in a Derby shirt. With no other clubs strongly linked, Derby were able to move quickly and secure the deal without distraction. So far in this season, Derby are conceding 2.33 goals a game (7 in 3), more than they'd like compared to the Championship standard. The hope is Eiran Joe Cashin adds a bit of steel and helps make them tougher to break down. Brighton continue to be linked with Femi Azeez, Yeremay Hernandez Cubas and Honest Ahanor while Derby are also rumoured to be tracking David Ozoh, Henrik Meister and Hamza Choudhury.
