Four on trial at Swansea
Cusack has already snapped up eight new players and is casting his eye over Jamie Wood, Marc Millar, Richard Hurling and David Theobold.
Wood is a former Manchester United trainee and arrives in South Wales after being released by Halifax at the end of last season.
He is a Cayman Islands international and the striker will be hoping to impress Cusack during his trial.
Scottish midfielder Millar spent time with The Swans towards the end of last season and brings with him a wealth of experience.
Fellow midfielder Hurling is a teenager who was recommended to Cusack after some encouraging displays for Llanelli.
Theobold was released by Brentford at the end of the past campaign and is a central defender who spent two years at Griffin Park.
Swans boss Cusack admits he has little to lose in handing the quartet trials but was making no promises about offering them contracts.
"In the case of the three more experienced players, I've been asked by their agent to take a look at them, which is what I am doing," Cusack told the club's official website.
"He is footing their bill, so it's not costing us a penny and similar to the trial match a few months ago, if anything comes from it, it's a bonus.
"In the case of Richard Hurling, he's local, he's been doing well for Llanelli, and he's been recommended to me by one of our scouts so I've decided to take a look at him.
"It's very much a case of nothing ventured, nothing gained."
