Linfield manager David Healy says his side's 1-0 loss against Limavady in the sixth round of the Irish Cup was "gut wrenching".
Ryan McNickle scored the only goal of the game in the 28th minute when he lobbed the ball over Chris Johns.
Linfield were denied by the woodwork on three occasions with the home side also striking the post in the closing stages of the game.
"Gut wrenching and sickening," Healy told BBC Sport NI after the defeat.
"Firstly, congratulations to Limavady and Paul [Owens] and, as disappointed as I am, we can't afford to miss the opportunities we did in the final third.
"We lacked intelligence, a bit of quality and our decision making was wrong. Our attitude in the first half wasn't quite there, in the second half we changed it slightly and didn't quite get the desired outcome. Hugely frustrating."
It has been a challenging season for defending Premiership champions Linfield, who currently sitting fourth in the table.
This time last year, the Blues were defeated by rivals Glentoran in the sixth round of the Irish Cup with Healy adding his side will "come back a little stronger" from their latest loss.
"You always feel in the situation and a result like tonight that you let everyone down, I wish I could have done more," he continued.
"One thing that I will do is get the team together, come back a little stronger.
"I have been in situations like this before when sometimes it gets worse before it gets better. Sometimes you have to take a few hits along the way."
