Dean Thomas admitted to feeling “fed up” as a familiar story unfolded for Kettering Town at Latimer Park on Saturday.
The Poppies slipped to a 1-0 defeat to Calor League Division One Central rivals St Ives Town as their interest in the FA Carlsberg Trophy was ended in the first qualifying round.
Kettering enjoyed lengthy spells of possession but were only really able to test visiting goalkeeper with long-range efforts.
And their inability to carve out any clear-cut chances when playing against 10 men for the last 24 minutes after Will Fordham was sent-off left boss Thomas thoroughly frustrated.
The only goal came just before the hour as Jared Cunniff sent St Ives through.
And Thomas said: “I am pretty fed up with all it really.
“People who know anything about the game would have walked away and said ‘at least they had a go, they tried, they created chances, they tried to do the right things and they worked hard’.
“That is all you can ask for sometimes but to cap it off, you have to win games.
“No one is going to roll over and die and everyone will work hard against us.
“I thought we dominated the first half and their goalkeeper has made some good saves to keep us out.
“And we still had plenty of possession in the second half. But the errors are killing us and every time we make a mistake we are getting punished.
“It rips the guts out of you. Their number nine (Dubi Ogbonna) was a threat all afternoon and we didn’t handle him very well.
“They got players behind the ball after they scored and that is what you have to do as a manager.
“You have to shut up shop and it was up to us to break them down. But we didn’t do enough in the wide areas in the last 25 minutes.
“Generally speaking, we have probably had 65 per cent of the possession but you have to find that final opportunity and we aren’t doing that at the moment.
“I can’t criticise the effort the players put in. The will is there but we have been done by individual mistakes again.”
The Poppies are straight back into action tomorrow (Monday) night when they take on Daventry Town - conquerors of Corby Town in the Trophy at the weekend - in the first round of the Calor League’s Red Insure Cup at Latimer Park (7.45pm).
