Tom Guest refused to make excuses for Saturday's capitulation to London Irish, and instead ordered his Harlequins teammates to sharpen up.
Quins stormed into a 20-3 lead after just 26 minutes at the Twickenham Stoop, through tries from Guest and Ugo Monye, and 10 points from the boot of Chris Malone.
But after conceding a sloppy try just before the break, Quins went on to have a second-half horror show and somehow contrived to lose 28-27.
And ahead of tonight's game at Worcester, Guest knows exactly what his team have to do to turn it around.
He said: "I don't think that tiredness is a factor, and our fitness is fine as we had a very good pre-season.
"It's more to do with game organisation and intelligence around the park, knowing what to do when we don't get the ball for long periods and when to put pressure back on.
"In the first-half, we were on top all the time, attacking hard and running well. But when you don't have the ball for a while you lose your focus and sharpness."
Despite letting a half-time lead slip for the second game in a row, Guest insists there isn't some kind of mental block coming out for the second-half.
He said: "We were dominant in the first-half and should have gone in 20-3 up, but gave away an easy try just before the break.
"But we were very confident coming out for the second-half. Everything was working well for us.
"Our running game was clicking, we were attacking their weaknesses, Chris Malone was kicking well and we were looking confident.
"But they played a lot better in the second-half and pressurised us. We didn't touch the ball for over 20 minutes and lost our way a bit.
"We couldn't get the ball away. It was similar to the Gloucester game, where we won the first-half but rarely touched the ball in the second."
Any more slip ups could cost Quins dearly as they embark on an exhausting week on the road with two away games in four days.
Following tonight's Premiership visit to Worcester (8pm), they travel to Swansea to take on the Ospreys in the EDF Energy Cup on Sunday (3.05pm).
Guest added: "We have an opportunity to turn things around at Worcester and bring our season back on track.
"Wor ce st er are looking hungry this year, and it won't be easy. But we will try and impose our attacking style on them and see if they can cope with it."
