Despite having had the upper hand in two cup ties against them this season, Michael Duff is warning his players they can expect a tough examination on Tuesday night when they travel to visit Gillingham.
Already this campaign the two clubs have gone head-to-head in cup competitions on three occasions - once in the Carabao Cup and twice in the FA Cup - with the last meeting coming last Tuesday.
This week's contest though is the first league encounter between the teams though and Duff knows all too well the task that lies ahead.
"They've had a difficult start. We've got a few injuries but they've got unprecedented injuries all over the park," he said.
"I spoke to Steve (Evans) before the game last Tuesday and he said he'd never known it in 30 years of management.
"You know what you're going to get with a Steve Evans team. If you don't run around and work hard and give everything for him you won't play for him.
"It's always a difficult game against any Steve Evans team no matter what numbers they've got."
