The Republic of Ireland Under-21 international is set to complete a move to Britain in the coming days and the Leesiders boss has praised his attitude
The Republic of Ireland international is close to sealing a move to English Championship side Brighton and Hove Albion, but a second bid was accepted on Friday evening.
Speaking to reporters after his side's 2-2 FAI Cup third round clash against Bohemians, Caulfield hailed the 20-year-old's attitude and said that he was "a credit" to Cork City.
"He's been a credit to his family and he's been a credit to the club," Caulfield said.
"To put up with being in the press day after day, he's kept his head, he's kept training hard and kept his form. He's been absolutely fantastic."
Meanwhile, Caulfield is pleased to remain in with a chance of winning the FAI Cup after his side snatched a late draw against Bohemians at Turner's Cross on Friday.
Owen Heary's side took the lead in the first half through Dinny Corcoran before Billy Dennehy scored from a penalty rebound late in the second half.
However, Bohs again assumed the lead when Corcoran met a Jason Byrne cross but Dan Murray's 88th minute strike ensured that both sides will contest a replay at Dalymount Park on Monday, August 25.
"They're great lads, with great character," Caulfield told reporters after the game.
"It looked like they were dead and buried but thankfully they just hung in there and got the equaliser. And maybe even at the death, we might have got the winner, it was that type of crazy game - but they could of got the winner as well.
"I think it was a fantastic cup tie, but certainly for the heart it wasn't great on the sideline."
