Chris Coleman is expected to rotate his squad as Wales' Euro 2016 casting call travels to Ukraine on Monday.
The absence of key players such as Gareth Bale, Aaron Ramsey and Hal Robson-Kanu has afforded Coleman the opportunity to take a look at some of his fringe players, with the deadline for nailing down his 23-man travelling party closing in.
The likes of George Williams and goalscorer Simon Church staked their claims for selection in Thursday's 1-1 home draw against Northern Ireland, while Danny Ward - expected to be included as part of a settled trio of goalkeepers - made his debut as a half-time replacement for first-choice Wayne Hennessey.
"These games are very important," Tottenham defender Davies is quoted as saying by BBC Sport. "There's a lot of places in the squad up for grabs.
"I think some boys staked a very good claim [against Northern Ireland]. There were some good performances from the boys that came on and these are games where you have to show what you can do.
"Ukraine is a good test for us. They're a top team and we're aware of what they can bring to the game."
Ukraine will view their encounter with Michael O'Neill's men in France as must-win as they bid to make it out of a group that also sees them go up against neighbours Poland and world champions Germany.
