Cardiff boss Ole Gunnar Solskjaer admitted he was very disappointed after his side's 2-1 FA Cup exit at the hands of Wigan.
The holders won at the Cardiff City Stadium thanks to first-half goals from Chris McCann and Ben Watson, with a Fraizer Campbell effort sandwiched in between.
Afterwards, the Cardiff boss was upset with his side's failure to convert chances into goals after dominating possession.
He said: "I wouldn't even say pretty disappointing. It's very disappointing, because we had the majority of the possession, the majority of the shots, more chances, but when you don't take chances you're not going to win games.
"The first goal to concede is a poor one. I thought it was a stupid foul to give away, then we don't clear our lines.
"We should have headed it clear, but the second goal we can't do anything about - that's a wonder strike by the kid. That was the two shots they had on target."
Despite losing to a team from the Championship, which Cardiff won and got promoted from last year, the Norwegian added: "They are a good side. They are the holders, he's (Wigan boss Uwe Rosler) done really well with them for the months he's been there.
"They play good football, they've got good players - probably got more Premier League experience than we have - so of course we didn't play mugs, we played a good team with good players."
Solskjaer can now focus on his side's Premier League relegation battle and, reflecting on how his side will tackle the challenge ahead, he said: "I don't know any other way than work hard, believe in what you're doing, don't feel sorry for yourself.
"That's the only way to get out of a bad spell as a footballer, as a team, as a club and that's what you've got to do.
"You've got to believe in each other, trust in each other and we've got a big, big game next weekend - Hull."
