Manager Roberto Martinez took Wigan's Carling Cup exit on the chin after they were dumped out 2-1 by Crystal Palace.
Championship side Palace were cruising at half-time thanks to goals from Darren Ambrose and 17-year-old Jonathan Williams. Wigan finally perked up in the last 20 minutes with Chelsea loanee Patrick van Aanholt - one of seven changes from the 3-0 defeat to Manchester City - hitting the crossbar before former Eagle Ben Watson scored in stoppage time.
Martinez said: "I felt we started well, probably too well. Then we switched off and defensively we didn't show real concentration or intensity and Crystal Palace took their two opportunities really well."
He added: "After that it was always going to be difficult. Crystal Palace were very well organised, they worked really hard off the ball. We tried everything but scored the goal a little bit too late.
"You have to give credit to Crystal Palace. We are disappointed with the manner in which we conceded our goals, but if you are going to lose, I'm happy in the manner we tried to get back into it and played the way we wanted to play."
Eagles boss Dougie Freedman appears to have unearthed a new star in Wales Under-21 midfielder Williams, who marked his second start for the club with his first senior goal.
"I can remember Ben Watson, at 17, playing in the first team here, and the progression he's made," Freedman said.
"So I am looking forward to seeing players like Jon doing the same, up to the Premier League, hopefully with us. He's a very good prospect."
