Wigan Athletic manager Roberto Martinez was left to lick his wounds after Saturday's 3-1 setback to fellow Premier League side West Ham United.
The Latics were undone as the men in claret and blue cruised into a 3-0 lead thanks to goals from Valon Behrami, Victor Obinna and Scott Parker at Upton Park before Tom Cleverley struck for the Latics with a late consolation.
But the Spaniard was unhappy with the nature of West Ham's goals, Mauro Boselli's penalty miss and a late effort from Steve Gohouri that was chalked off.
"In a way, we knew how important the game was and in a way goals are the biggest aspect of the game and obviously, the three goals which we conceded were very cheap," he said.
"We didn't start too bright, but we were slowly getting into the game, but then, when you concede a goal, it's such an emotional day in terms of the importance that the first goal is very important.
"Even then, we kept trying to get back into the game but we left ourselves exposed and we conceded another two goals before the end.
"Then again, you look again. A certain bit of luck with some decisions. We missed a penalty and had a goal wrongly disallowed and that's hard to take. I just felt the reaction at the end deserved more than losing.
