Dagenham & Redbridge manager Wayne Burnett can accept the frustration of supporters following a run of one win in 10 matches in all competitions.
The Daggers, who are three points above the League Two relegation zone, were knocked out of the FA Cup by Conference side Southport on Tuesday.
"Why would you be happy?" Burnett told BBC London 94.9.
"They want to put their anger towards someone and that is me as I pick the team. I have to get over it."
The east London side lost their first-round replay 2-0 at Haig Avenue after having midfielder Luke Howell sent off for violent conduct at the end of the first half.
"I tried to go over to the fans and have a chat with them at the end because I understand their frustration," Burnett added.
"I am not trying to justify it because we have been beaten. We were not in any danger up to the red card and it changed the complexion of the game.
"A Cup run would mean everything to this football club. People know our finances and resources are tight and it would have been good."
Burnett was handed a two-year contract by the Daggers last summer following a spell in interim charge and led the club to ninth place in League Two last season.

The side are currently languishing in 22nd place in the table, having won four of 17 league games in 2014-15.
Although Burnett believes he retains the support of the club's board, he is wary of the need to improve results.
"I haven't had any discussion with them at all," he said.
"This board have been absolutely fantastic and supportive towards me. They have been over the years to all managers who have been here but I have to win matches.
"We are third-from-bottom but that probably reflects where our budget is to be honest. We over-achieved last year and I don't want to lose sight of that fact.
"We don't want to be in that position because it is not a nice position to be in. No-one does.
"We are in a trough but we have to pick ourselves out of it."
