The Pools boss completed the signing of experienced goalkeeper Kyle Letheren last week after his exit from Morecambe with the 34-year-old joining as a player-coach to complement the backroom staff as well as provide competition in goal for current No.1 Ben Killip.
Hartley and Letheren go back to their time together at Dundee in 2014 where Hartley spent three years in charge at Dens Park.
The Pools boss spent a decade in management north of the border across four teams earning five promotions along the way.
But following the signing of a former player in Letheren, and links to another ex-player in defender Reghan Tumilty, here at The Mail we look at some of Hartley’s former players from the teams he has managed and who he could look to reunite with at the Suit Direct Stadium.
