Killian Brennan (ex-Shamrock Rovers), Conan Byrne (ex-Shels) and Dave Ryan (Limerick) all have a proven League of Ireland pedigree but former Ireland U19 cap Murphy is still waiting to deliver on his early promise.
The former Middlesbrough trainee, who was part of the Ireland U19 side which reached the semi-finals of the European Championship finals in 2011, had a difficult time last season; his move from Bray Wanderers to Monaghan United turned into a nightmare as Monaghan went bust, and a subsequent move to Derry City was also difficult as injury and loss of form saw Murphy restricted to a handful of appearances, while he was also unable to take part in City's successful FAI Cup run as he was cup-tied.
But Buckley feels the ex-Bray man has a bright future. "The best is yet to come from Conor, I know that," says Buckley.
"I know last season wasn't easy for him, with all that happened during the year, but he has real talent and has great ability. He is an underage international and has also done well in the League of Ireland when he's been given a chance.
"I look forward to working with Conor as I feel that our coaching staff here can get a lot more out of him," added Buckley.
Despite the arrival of seven new faces to the Saints squad (Shane McFaul, Killian Brennan, Sean Gannon, Conan Byrne, Pat Flynn, Dave Ryan and Conor Murphy), Buckley says he's still on the hunt for players and hopes to add two or three more fresh faces before the new season starts.
