The Pools boss has wasted little time in rebuilding his squad at the Suit Direct Stadium with, at the time of writing, 12 new additions to the squad after the loan signings of Walsall defender Rollin Menayese and Livingston striker Jack Hamilton and the permanent deal for Mikael Ndjoli.
But Hartley insists he has not finished with his business in the transfer market as he continues to seek further reinforcements to his side.
And, as with every transfer window, Pools have been linked with their fair share of players over recent months.
Some of those players have completed their moves to the Suit Direct Stadium whilst others are yet to agree moves from their current clubs.
And, here at The Mail, we take a look at some of those players to have been linked with Pools who are still to confirm their transfer future.
