Anders Lindegaard has described Manchester United's "bad habit" of falling behind in matches this season as a major concern at Old Trafford.
When Jamie Mackie put QPR ahead at Old Trafford on Saturday, it was the 13th time this season United had gone behind.
The reply, through Jonny Evans, Darren Fletcher and Javier Hernandez, ensured it was the ninth occasion when United have been able to salvage the situation and claim a 3-1 victory.
However, Lindegaard knows it is something United have to address - and fast - if they are to still be challenging for the Premier League title in the spring.
"We should be concerned. It is a bad habit," said Lindegaard.
"We have to look at it.
"I just asked one of my team-mates afterwards, 'what would have happened if we hadn't conceded a goal?' It was like a wake-up call.
"It is a bad feeling to have conceded a goal in this match. It is very disappointing."
The sight of Nemanja Vidic wandering through the Old Trafford stands prior to kick-off underlined the organisational skills being missed so badly in the Serbian's absence.
It is thought Vidic is approaching a return to first-team training following his knee operation, although by the time he does return he will have been out of action for 12 months save for the five matches he was involved in at the start of the season, and his fitness cannot be taken for granted.
Instead, Sir Alex Ferguson must place his trust in Rio Ferdinand, Evans, Chris Smalling and Phil Jones to sort the matter out between them knowing there are other areas of concern as well.
One revolves around Paul Scholes.
The 38-year-old is still capable of moments of inspiration that turn matches on their heads. However, he clearly lacks the energy required to be a physical threat and it was not until Scholes was replaced by Anderson after an hour that United really got going.
"Anderson turned the match around," said Lindegaard.
"He is one of the best players in the world at running with the ball, passing it and keeping the dynamic motion.
"He is a brilliant player."
Rarely has Anderson managed two high-class performances on the trot and even within games the 24-year-old is capable of going from the sublime to the ridiculous.
Of his seven Premier League appearances this term, only one has been from the start and he has not completed the full 90 minutes in a league match since September 2011.
There have been vague insinuations Anderson's fitness is lacking and despite all the high-tech sports science techniques, as former United goalkeeping coach Tony Coton said on MUTV: "Once they leave the training ground, you can't go with them.
"I am not saying this is his lifestyle, or it is a problem. But you can't live with them 24 hours a day so there may be something that is occurring out there that we don't know about."
In addition, Hernandez provided yet more evidence for the argument he is a better substitute than a starter after his lacklustre displays against Norwich and Galatasaray.
And if that was not enough, Lindegaard's selection ahead of David de Gea in goal suggested Ferguson is still not convinced by the young Spaniard, even though, before having his wisdom teeth out recently, it seemed he had again secured the number one berth.
"The tendency lately is that David has played," said Lindegaard.
"Unfortunately for him, he has been out with a teeth problem which I am trying to benefit from.
"I still don't see a clear picture on how things are going to develop throughout the season.
"It is not more than a week ago I read in a Danish paper that 'Lindegaard had lost the battle', which says a lot about how ignorant they are."
