Forest were able to name a strong bench for the friendly against Birmingham City and boss Davies told BBC Radio Nottingham afterwards: "It shows you the difference from last season when we were putting on a lot of young kids."
Defensive signings remain the final piece of the jigsaw for Davies, whose side take on Reading in the season opener on Saturday.
Matt Mills of Doncaster Rovers remains the most likely new signing although a fee remains a stumbling block.
