Davies wants to force Villa boss Martin O’Neill to hand him a new contract.
Davies joined Villa in a £11million deal from West Brom, but has been placed on the transfer list this summer.
He said: “The biggest thing for me is getting back into the team.
“I am going to roll my sleeves up and see what happens. Obviously the manager will make his decisions but I will see, keep my head down and hope things work out for me.”
“I have never been scared of competition. I have done a lot of hard work and a lot of running throughout the holidays. Now I’ve come back for pre-season one of the fittest here and determined to make it work,” he added.
“We’ll have to wait and see. If I can get in the team ahead of the likes of Carlos Cuellar, Richard Dunne and James Collins you know you must have something right in pre-season.
“If I can put in a couple of good performances against Feyenoord and Benfica, hopefully that will stand me in good stead for the start of the season.
“If I play well I can give the manager a massive headache and that is what I want to do.”
