Newport County boss Graham Coughlan is convinced the home support will be a factor against Manchester United.
Newport host United in the Fourth Round of the FA Cup on Monday night.
"You can hear everything. Sometimes you don't want to hear," he said.
"It is hostile, it's noisy and when they get going and start beating that drum, it's an atmosphere to savour.
"Irrespective this season of whether we've been winning, losing or drawing, our fans have got right behind us.
"At times, our fans have dragged us over the line, they've dragged points and wins out of games where we didn't think it was possible. The noise that they make, they're so supportive."
