Wycombe Wanderers boss Gareth Ainsworth was "flabbergasted" at his team's second-half collapse after a 2-0 loss at Newport County plunged them closer to the relegation zone.
Christian Jolley and Chris Zebroski struck in the space of six minutes in the second-half at Rodney Parade to add Wycombe's away misery.
The Chairboys are without a win in their last 6 games on the road and are now only outside of the relegation zone on goal difference ahead of Northampton, who they face next week.
Wanderers manager Ainsworth said: "We had the majority of chances in the first half but I didn't recognise my team in the second.
"I don't know what happened, we fell to pieces. We looked nervous and a team who didn't know each other. We were nowhere near the team that beat Dagenham & Redbridge last week.
"I'm just flabbergasted at the second-half performance.
"The nerves come from where we are in the league and we're a very young team. But we have been a young side all season and I thought that would give us legs and enthusiasm, but I didn't see either of those things today.
"We were out-fought and in a scrappy game like that, you have to win your battles, your headers and tackles, but we didn't and we paid the price. That result has given us a real battle."
Rene Howe flicked on Ryan Jackson's long throw and Jolley tucked the ball inside Matt Ingram's near post on 65 minutes and Howe then supplied Zebroski who fired into the top netting on 71 minutes to put the game beyond the Chairboys.
The victory was Newport's first win at home in 10 attempts but should be enough to secure their place in League Two following promotion last season.
Assistant manager Jimmy Dack said: "Before the start of the season 99 per cent of our fans would've been happy with staying up and we raised those expectations.
"So we needed to win today. The pressure is always on us at home but we needed this result because a win at home has been a long time coming.
"We didn't make any mistakes, looked accomplished and it could've been more than 2-0 but we were nervous at the start
"The boys haven't hidden, they've kept plugging away and we will try and kick-on with as many points as we can."
