Graham Coughlan blasted the officials for denying Newport “a very legitimate goal” in their 2-1 defeat to Salford at the Peninsula Stadium.
Salford took the lead thanks to Matthew Lund’s 25th-minute header but Bryn Morris’s strike levelled things six minutes later.
An unfortunate own goal from Declan Drysdale put Salford back in the lead just before half-time.
The visitors thought they were level again on the hour, but Will Evans’ goal was disallowed and the Newport winger was booked for protesting to the linesman after he flagged for offside.
Exiles boss Coughlan said: “We scored a second goal which was a very legitimate goal. I don’t see what the issue is with it.
“We’ve looked back at it and we can’t see where they’re coming from, so we’re absolutely fuming to be honest. Decisions like that don’t belong in the game, someone needs to look at the decision and give us an honest explanation as to why the goal has been disallowed.
“There’s no excuses, you can’t disallow that goal but these guys get protected and that needs to be explained because it’s not good enough and we expect better.
“In my eyes, it’s a 2-2 draw today.”
Coughlan did also concede that errors cost his side.
He added: “We made two basic, silly errors and if you don’t make them errors you win the game today. I thought our performance overall was excellent, but we have to look at the errors and we have to look at the two goals that we conceded.”
Salford came into the game off the back of six straight defeats – a run that Neil Wood was relieved to put an end to.
Ammies head coach Wood said: “It was always going to be a battle to get back on track. We knew it was going to be a day like that and we were much better in that department than we have been in recent games, which was a positive for us, and it’s a relief.
“When we play quickly and we attack quickly, it’s a really high level to see. We need to make sure we are strong and difficult to play against. All of the things we looked to address this week in training, there was a large improvement.”
Salford travel to Gander Green Lane on Tuesday night to play Sutton, who currently lie at the foot of Sky Bet League Two.
Wood said: “We have to go to Sutton and put the same energy in, defend the same way, and when we get our moments create some chances.
“It was nice to win a game, but we have to go and do it again. We look forward to Tuesday night and next weekend and we have to win.”
