Despite the goal, McCulloch was unhappy to lose the game, especially with the two goals "given away".
McCulloch said: "It was a scrappy start for both teams and it was good to get in at half time 1-0 up, but we are bitterly disappointed at having given away two sloppy goals.
"I can't remember too much about the goal. Jimmy Bullard just slipped the ball through to me and I fancied a shot and I just hit it perfectly, and luckily it went in the net.
"The gaffer has told us that anytime you think about having a shot, make sure you hit the target, and I did that!"
Next up for the Latics is a trip to Ewood Park for a difficult game with Blackburn Rovers. The match will be played in front on Sky's cameras on Monday evening in a game that could go a long way to deciding our European fate.
