Speaking to City Studios in an interview after the game, O’Reilly made special mention of City’s character to complete the impressive turnaround.
“Everyone wanted to get on the ball, everyone wanted to play. I’d say there was a lot of character out there tonight. I think that’s what got us over the line.
“We knew we could get goals back, so that wasn’t the problem.
“We just had to stay focused, not be scared by the environment and the counter attacks they were causing. And that was it.
“We’re all on a high right now. We need to keep pushing and keep going.”
O’Reilly also spoke about his delight at getting on the scoresheet and stressed the importance of pushing for a top-eight finish in the League Phase of the competition.
