QPR boss Marti Cifuentes admitted his side performed dismally in their 2-0 loss at Millwall.
The defeat was their third in a row and they remain in the relegation zone, with Huddersfield’s win later in the day leaving Rangers five points from safety.
“It’s a poor performance – perhaps the worst since I’ve been here,” Cifuentes said.
Tom Bradshaw’s simple finish just before half-time opened the scoring and Murray Wallace’s late goal after a mistake by Asmir Begovic sealed the Lions’ win.
George Saville found himself in space on the left of the penalty area and sent the ball low towards the far post, where Bradshaw drifted in behind Jake Clarke-Salter to score the opener.
And when keeper Begovic hopelessly flapped at George Honeyman’s left-wing corner, Wallace got in front of Osman Kakay to bundle in the second.
Rangers had plenty of possession but once again struggled to create chances, with Lyndon Dykes up front offering no real threat.
Cifuentes admitted: “We didn’t start the game well. Millwall pressed really, really high, were very aggressive, and we didn’t find a way to beat that pressure.
“We lacked the capacity to understand the space today was behind their back line. We had to activate the runs from behind.
“From minute 30 we started to understand this a little bit better, but then in a minute (just before half-time) that we should never concede a goal, we conceded a goal.”
