Dunfield has fully recovered from knee surgery and is now preparing for preseason trials as he bids to return to the game.
City chief Jim Cassell told the club's website: "He's now back in this country and actually training with our Academy at the moment.
It was further help from Cassell that gave Dunfield another chance to prove himself and he is certainly grateful.
The midfielder added: "They have welcomed me with open arms [at the Academy]. Alex Gibson, Paul Power and Gregor Rioch have let me join in with training sessions, it's like I'm a player there again so it's fantastic for me.
"I had been going for rehab work at Lilleshall once a month, but Bernard Halford said he would see what the Club could do for me. All the staff at Platt Lane and Carrington have been fantastic, and I can't thank them enough."
Ten years on from taking Dunfield under the Club's wing originally, Cassell remains hopeful of adding the string of another footballing success to an already bulging bow.
"He's certainly still young enough at 25 and he's learned from certain things the last time around.
"I would love Terry to bounce back and earn a living out of the game because he has got immense ability."
