Glen Clarence says his high flying Heanor Town team are yet to adapt to the officiating in the Midlanf Football Premier.
The Lions had another two players sent off on Saturday, but still came out on top in their battle with Highgate United.
The 3-1 victory put Heanor joint top, until Hereford went three points clear - having played more games - on Tuesday night.
Clarence was particularly annoyed with the sending off of Danny Claridge, with video footage showing he had made a perfect, if robust challenge on a Highgate player.
“Saturday was a good result as Highgate are right up there,” he said.
“This time we had to do it with nine men but I stand by the players, this league is the polar opposite of the Northern Counties and we simply haven’t adapted to that.
“Cards are being shown for anything and the red card for Danny was so wrong - it was a perfect tackle.
“Thankfully we now video the games and have appealed to the FA with video evidence.”
Clarence has been left in a difficult position, unable to tell his players not to challenge for the ball, but unable to continue to watch them get red cards.
“We’re obviously struggling to adapt to the way it’s officiated, and can’t tell players not to tackle.
“We just hope to have a bit more luck on that front, because like I’ve said, watch the video, it’s not a red card for Danny.”
Heanor, who were due to take on bottom side Continental Star on Wedesday night as the Ripley and Heanor News went to print, have lost just once so far this season in the league.
The manager isn’t getting carried away, but admits it’s a good start to life in a new league that is every bit as competitive as the Northern Counties East League Premier that Heanor left in the summer.
“I’m obviously very pleased with the form, and if we beat Continental Star we’ll go second.
“But there’s a few teams in a smiliar position so it proves how much of a tough league it is.
Heanor host Walsall Wood on Saturday.
