Millwall boss Neil Harris reminded his players of the standards needed after Easter Monday's 2-2 Sky Bet Championship draw with Ipswich Town at Portman Road.
Jake Cooper gave The Lions the lead in the first-half in Suffolk, but Martyn Waghorn's quick-fire double sent The Tractor Boys into the lead.
George Saville, however, notched his 10th goal of the campaign on the hour-mark to secure a point and a 14th match unbeaten.
The manager expressed his frustration after the game.
"I'm quite frustrated, to be honest. Ipswich made the game what it was - counter-attacking and very open by the formation that they played, leaving players up the pitch at any opportunity," he said.
"It's not a favoured game of mine, playing like that, but it was what it was. When the game is like that, you have to make sure you outscore your opponent. It's hard to criticise my players because of the run we're on and the form we're in, but if I want to set standards as the manager of this football club, then I have to tell them that wasn't good enough."
An end-to-end second-half culminated in the visitors missing a glut of chances to win the game - something that didn't go unnoticed with the boss.
"We should've won the game. Today, we missed countless opportunities and the goalkeeper - one of the best in the division - made many saves. We gave two poor goals away, but we, as an attacking team, needed to get the defence out of a hole with that one.
"We should've scored seven in the last 10 minutes of the game and not to get at least one was criminal.
"The two goals conceded were avoidable by us. Having said that, individually, we give very few goals away, hence the third best defensive record coming into the game. So, when they do that, we have to make sure we get them out of a hole by scoring, where we just fell short."
The points ensures The Lions remain in eighth place with six matches remaining in the Championship season.
"That's the fine margins - we could've scored numerous goals in injury-time, we didn't, but Middlesbrough did, so they stay above us. That's the frustration. I hope I look back at the end of the season saying that's a point gained.
"I know my fanbase have gone home happy, singing the players' names off the pitch - it's important to know they enjoy the effort my players put in. But it's my position as the manager to set standards and demand more. Today, I wanted three points and we should've had them."
