Paul Dickov cut a disappointed figure after his Oldham side surrendered a two-goal lead to lose 4-2 to Sheffield Wednesday in the first round of the Capital One Cup.
Goals from Jordan Slew and Jean-Yves Mvoto stunned the Owls before the break, but Dave Jones' men rallied to progress to the next round thanks to goals from Jermaine Johnson, Chris O'Grady (2) and Michail Antonio.
Dickov said: "When we do things right with and without the ball, we're a decent team who play good football. But towards the end of the first half we got a bit giddy and we stopped doing the things that had helped us go 2-0 up.
"We knew Sheffield Wednesday would come out fighting after half-time and we lost our team shape when it happened.
"We stopped getting Jordan Slew in behind their defenders and we couldn't get players like Robbie Simpson and Lee Croft on the ball.
"We were excellent for most of the first half, but it has to be a 90-minute performance - in the second half Sheffield Wednesday did to us what we'd been doing to them.
"The goals we conceded were poor and we need to learn from it, but I suppose it's better for this to happen now instead of in the league."
