BANGOR City manager Nev Powell branded his side's Welsh Cup performance in a 2-1 defeat at Holyhead Hotspur as "unacceptable".
"The level of performance was not what is expected, particularly by the Bangor support," he told the club's official website.
"I know what it means to the fans out there having played and managed the club for so long. I'm as angry and frustrated as anyone else by last night’s result. I've also let the players know that.
"It's clear the squad are missing the suspended Anthony Miley and Rio Ahmadi and that's something we have to deal with."
Powell acknowledges that the club is now under pressure but urged the fans to get behind their team for this Saturday’s live televised Welsh Premier fixture against Newtown.
"I’ll be looking for a reaction from the players on Saturday and hope the fans can get behind them too," Powell added.
