Chris Plummer felt Corby Town “left the back door open” for Bishop’s Stortford as he saw his team slip to a second successive 2-1 defeat in the Blue Square Bet North.
Having been beaten by a late goal at Chester in midweek, the Steelmen suffered a similar fate in Hertfordshire as they were sunk by Blair Sturrock’s 89th-minute winner.
Plummer’s men had fought back to level thanks to Ryan Semple’s header after the hosts had taken the lead in the first half.
But, despite enjoying plenty of possession, they were unable to find a winner and were undone by what the Steelmen boss described as “a sucker punch”.
“On the whole I thought we played really well and we were in control of large parts of the game,” Plummer said.
“They scored a very good goal in the first half but we bounced back and then we have been hit with a sucker punch at the end.
“But over the 90 minutes, if we had come away with a draw it would have been the least we deserved.
“We were really pushing for a goal but we gave the ball away in a bad area and they were straight at us. We left the back door open for them.
“We will look at and learn from what we have done in this game. But there is no point worrying or stressing about it too much.
“We will go again next Saturday and we will work hard to prepare for that game with Hinckley.
“We are not a million miles away, we just need to cut out the silly mistakes. I am not too worried.”
Plummer, meanwhile, is fearing Stefan Galinski’s three-month loan stint from Derby County may be over a week early after the central defender limped off with an ankle injury in the second half.
He is already a doubt for next weekend’s home clash with bottom side Hinckley United and, with Carl Piergianni facing a two-match ban due to start the following week, the urgency to find at least one new centre-half is now increased.
Plummer added: “Stefan has got a bit of inflammation across his ankle, it looks a sore one.
“It may well be that was his last game in this loan spell but we will assess it over the next 48 hours and see whether it settles down.
“My understanding is that Carl is banned for two games after he was sent off at Chester.
“Obviously there is a bit of a gap in our side in that position especially with Stefan going back after next week and potentially being out for Saturday any way. It is something we are looking at.”
