With O’Connor expected to replace the departed Derek O’Brien on the left wing, Dunne is looking for an attacker to replace Graham Cummins, who has signed for Preston.
“Obviously, with Graham going we’re a bit thin up top,” he said. “I think everywhere else on the park we seem to be well covered and with Shane coming in it’s a piece in the jigsaw on the left-hand side.
“If we could get a striker, that’s what we’re looking to do, and I’ve spoken to one or two people. We’ve signed Vinny Sullivan back but we are looking to bring in one or two others.
“Realistically, we’ve only three front men at the moment, Davin O’Neill, Jamie Murphy and Vinny so we’re looking for another striker to give us an opportunity to compete.
“It is a step up but we want to be competitive, it is a natural thing in Cork that it’s expected regardless and we’ve no problems with that.”
For O’Connor, formerly of Liverpool and Ipswich Town, the return to his hometown club allows him to get his career back on track and hopefully return to England in the future.
“Obviously the ambition was always to go to England when I was younger,” O’Connor said, “and it’s probably still there now. “I feel that I’ve unfinished business over there and I want to progress. Coming back to Cork will give me the best opportunity to go back to England. I did have other offers but they would have been to play left-back and left-midfield has always been my favourite position.
“To come here and have the chance to play there helped swing it for me.”
City also yesterday announced that Clonakilty Food Company had taken over as the club’s main sponsor, with the Clonakilty Black Pudding logo to feature on home and away strips for the next three years.
