Mark Yates described Lee Thompson's missed penalty as the turning point in Kidderminster Harriers' goalless draw at strugglers Forest Green Rovers.
While manager Yates admitted the result was fair in a game of few chances, Harriers had the perfect opportunity to snatch victory when they were awarded a harsh-looking penalty seven minutes after half-time.
Forest Green defender Michael Taylor was punished for an innocuous challenge on Andy White, but keeper Ryan Clarke, a former Harriers loanee, blocked Thompson's spot-kick and then flipped over the follow-up.
"I've got no problem with people missing penalties because at least he was brave to take it - although I'm not sure Thommo will be taking any more," said Yates.
"I think if we had scored we would have gone to win. We coped well with the pace of their strikers but the disappointment of the penalty miss seemed to play on our minds. We never got going after that.
"A point is probably the right result after a scrappy game."
Tamworth manager Mark Cooper invited a furious fan to have his say in the dressing room as the relegation-battling Lambs crashed to a 5-0 rout at Grays Athletic.
"A shocking performance" was Cooper's own verdict but the Lambs boss let the supporter put his own frustration into words in the dressing-room afterwards.
"The fan has paid £30 to get here and he deserved his say," said Cooper.
Despite the inclusion of new recruit Tommy Johnson, the Lambs trailed 2-0 inside 28 minutes after Aaron McLean and Stuart Thurgood netted and a bad day became a nightmare when Dave Bampton's second booking meant he was sent off two minutes later.
Jamie Slabber struck either side of half-time and Michael Kightly made it five to leave the Lambs without a win in seven matches.
"My players should feel embarrassed, especially the seniors," said Cooper.
