"I was imagining, if we'd lost, having to watch that over and over again on the FA Cup's Biggest Shockersg," he told the Echo.
"I was envisaging having to see it every year for the next 20 years to be honest.
"But I did feel I was being fouled. I felt a tug from behind, I tried to take it with my right and it just spun off my foot and I fell over. It was one of those freaks.
"I'd never scored an own goal before I came to Cardiff and that is my second now in competition and I've scored one in a friendly.
"It was important we went in 1-1 at half-time - if we hadn't the pressure would have kept mounting.
"It was their cup final. They worked their socks off. Even though there is a big gap between us, it was always going to be difficult.
"It wasn't great out there with the pitch, the wind and the sun in our eyes, but we got things together second-half.
"Before the game, we would have taken 3-1 any day, as long as you are in the draw for the next round. It was a difficult task, we might not be happy with the way we played, but we are just happy to get through."
