"We're very disappointed, we controlled game, especially in the first half, but their first goal was soft," BBC Sport quotes him as saying. "After that we could not get a foothold. The second goal was a hammer blow, we thought we'd done enough. We just hope the other team does us a favour.
"It was the story of our season, we create so many chances but don't put them away. We should have been home and dry, especially at half time.
"We're Wigan we like doing things the hard way. Hopefully the other result will go our way."
Wigan are now third in the Group D table, having been overtaken by tonight's opponents.
