Burton boss Paul Peschisolido would like to offer contracts to trialists Jack Dyer, Lewis Young and Garyn Preen.
However, the Canadian is unsure whether the club`s budget will stretch to three more signings.
"From what I have seen of these boys in training and during games they are all desperate for a new club," Peschisolido told the Burton Mail.
"I would like to accommodate them all if that is possible but that is something I am going to have to sit down and talk through with the chairman.
"They have all got ability and a great attitude and it is obvious that they have been well-schooled at their previous clubs."
Preen could feature in the friendly against West Ham on Saturday after resting a groin strain.
