Plymouth boss John Sheridan spoke of his hurt after seeing his side lose 1-0 to 10-man Hartlepool.
A fine Luke James effort won the match but Argyle could not break down a Pools side who were a man light from the 25th minute after Jack Compton was sent off.
Pools were still too good for Plymouth who have now gone seven without a win but the home side had goalkeeper Scott Flinders to thank for the points.
The shotstopper was the star of the show, keeping out a number of efforts from the visitors, who were unable to break through, much to Sheridan's annoyance.
"It's very frustrating after they were going down to 10 men after, what, 20 minutes or so," he said.
"But even with 11 men, we were good. No excuses, we created chances, lots of them, and their keeper has kept them in the game.
"We've not took our chances and it's cost us. I cannot fault us, we tired to score, keep the ball moving and created really good chances. The game should have been over."
He added: "I can laugh about it, but I'm hurting inside. Against 10 men we should have seen it through. A lack of concentration cost us, it was a poor, poor goal to concede.
"A young kid, 18-years-old, and he has gone past three defenders and we've made it look easy for him. They get a goal and it gives them a bit of belief they can win it. They get men behind the ball and defend with their lives.
"The keeper makes great saves, but no excuses, I'm not looking for any. It was a very very poor result."
