It means City end our summer friendlies with a 100% record following the victories over Preston North End and Barnsley.
With Bernardo Silva back in the squad for the first time since his summer break, Pep Guardiola’s side took the lead when Edozie steered a loose ball over visiting goalkeeper Stuart Moore from six-yards.
Blackpool equalised from the penalty spot, with Luke Garbutt firing emphatically into the top corner after Ruben Dias tripped Shayne Lavery, but Mahrez arrowed into the bottom corner to put City back in front shortly after the break.
The Algerian then picked out the unmarked Gundogan with a quick free-kick and the German midfielder applied the finishing touch with a smart first-time finish, before adding his second and City’s fourth from close range following a good ball from Joao Cancelo.
