It happened again for Chelsea - and perhaps the most damning situation of all is that you could see it coming a mile off.
Liam Rosenior's side threw away yet another lead at Stamford Bridge - this time dropping two points to second-bottom Burnley at home.
The Blues were dominating the game at 1-0 after Joao Pedro's opener but Wesley Fofana's red card caused instability. Then the Burnley pressure built until Zian Flemming headed in a stoppage-time leveller - and the Clarets missed more chances to win it.
Chelsea still go up to fourth - for now - but this was a huge opportunity missed, given the tough fixtures Rosenior's side have coming up. More on that below.
And while Rosenior rebuffed questions around the side's mentality, he did note Chelsea have five big problems right now:
In a passionate press conference where Rosenior outlined all his teams problems, read all of these issues analysed below....
Giving up commanding positions in games
After Sunderland and Leeds came from behind to win and draw, respectively, Burnley have completed the set for promoted sides battling back for rewards at Stamford Bridge. Crucial points Chelsea could count the cost of come the end of the season.
It's now 17 points Chelsea have dropped from winning positions at home - only once, in 1995/96 (20) have they thrown away more. They'd be top of the table with those points on their tally.
ROSENIOR SAYS: "What has happened with me is we have set fire to four points from two home games. Anyone watching the game, it's not good enough for a club of this level.
"It's not good enough for me to come and say we were the better team. We need to be the better team in every game. We need to win games of football.
"I know what the answer is and we will address it in the week. There's an inquest after every game, whether we win or lose.
"I'm learning about the players. I'm learning about the people you can lean on when things aren't going your way and you need to see a game out. That's something we need to address very quickly."
Wrong decisions made in attack
Throwing away leads is not just a defensive responsibility, it was an attacking one.
After going ahead against Burnley through Pedro's early opener, Chelsea were in complete control of the game. In the second half, Burnley failed to manage a shot until the red card.
That's despite Cole Palmer getting into good areas of the pitch but his touch let him down on multiple occasions. He even had a one-on-one in the first half that went begging - in the same end where he missed an open goal against Leeds.
Chelsea ended up with an xG of 1.88, highlighting how they should have got a second goal.
ROSENIOR SAYS:" From the first goal, we lacked incision when we had control. I want incision. I want us to create wave after wave of attack.
"We were too safe in our possession.- When you give a team, any team, a one-goal advantage, anything can happen. I think the frustration is more the last two home games, from being in winning positions and being in control of the game, to not win the two games.That's the biggest frustration. It's not a blame on an individual.
Red cards
It doesn't help when you've had eight red cards across all competitions. It's six in the Premier League and one more will break a club record.
The last time a Premier League team had this many red cards across all competitions was in 2015/16 - when West Ham dropped out of the top-four race and finished seventh. It's a real possibility for this Chelsea team.
ROSENIOR SAYS: "That wasn't on Wes, [against Burnley].
"That was an unfortunate red card for Wesley who steps on a challenge. I felt there was something that could have been dealt with better before that happened by the referee and went unnoticed.
"But you're going to get red cards. It's too many. It's too many for sure. But in my time with the group, I think our discipline record has been very good up to now."
Defending set pieces
Had Chelsea just held on to their 1-0 lead, nobody would have been talking about the above issues, including their red card record.
But the Blues did throw away a lead - and it came from a set piece as Zian Flemming headed in unmarked. It could have been even worse for Chelsea, had Jacob Bruun Larsen fired in moments later - missing the chance to make it 2-1 from a similar position, heading over instead.
It has been the story of Chelsea's season. Overall, 38 per cent of the Premier League goals Chelsea have conceded have come from dead ball situations - it's the third-highest percentage in the league.
ROSENIOR SAYS: "We knew their biggest threat with Wall Prowse on the pitch was set plays. We went as big as we possibly could because that was the only way they could score with 10 men. We still don't see it out.
"It is unacceptable for their best header of the ball to be free in the box. It is not enough clean sheets and not enough basic and values of defending set-pieces.
"There were players on the pitch who were assigned to do their job and who didn't do their job. That is what cost us the two points.
"Set plays are massive in the Premier League, they're so important. Our record this season, defending set plays, is not to the level which is required for us to achieve what we want to achieve and that's something I need to address."
They are likely to slip down the standings by the next time they play. Liverpool can go level on points with the Blues if they win at Nottingham Forest on Saturday. Man Utd will go back ahead of them by avoiding defeat at Everton.
Players lacking accountability in defence
Chelsea's head coach listed four matches during his time at the club in which the club have conceded goals from a lack of "concentration or accountability" to manage the situation.
Those matches included the recent wins over Crystal Palace and Wolves - but Chelsea are now dropping points as the other two games he mentioned were the recent draws to newly-promoted sides Leeds and Burnley.
ROSENIOR SAYS: "In my time here: Wolves away, Crystal Palace away, Leeds at home and today, where we've conceded goals from moments of lack of concentration, lack of accountability.
"If we want to maximise the potential, which I know is there, we have to address that very quickly.
"I'm learning about the players. I'm learning about the people you can lean on when things aren't going your way and you need to see a game out. That's something we need to address very quickly."
And it doesn't get any easier for Chelsea...
The game against Burnley was also particularly important because of what comes next for Chelsea. A brutal fixture list follows - starting with an away trip to Arsenal in the league, live on Sky Sports - the best set-piece team in the league.
Just take a look of their opponents going up until the end of April - and they still have to play Liverpool and Spurs after that...
