Doncaster Rovers manager Dean Saunders was less than happy with his side's defending in their 3-0 defeat to Leeds.
The home side more than held their own in the first 20 minutes before slack marking allowed Danny Pugh to open the scoring.
Ross McCormack's sublime overhead kick doubled Leeds' tally before Tom Lees got the better of Richard Naylor to head home a third.
Saunders felt the players' heads dropped and that for a passing team his charges gave away far too much possession.
Doncaster travel to Blackpool next week and the Welsh tactician is looking for a response from his troops at Bloomfield Road.
"I was a bit disappointed. I thought they (the players) dropped their heads a little bit," he told Sky Sports.
"We conceded three terrible goals. There was nothing in the game in the first 20 minutes.
"I thought we looked in control of the game at the start, the first 10, 15 minutes.
"To concede the goal that we did, George (Friend) has given a foul away in the corner where (McCormack) is facing the touchline going nowhere then the (Pugh) has tapped it in five-yards out on his own. That won't be happening again.
"The second goal was a bit of build-up play. McCormack's sharp brain has got in behind out back four and he's finished it well with an overhead kick.
"Then the third goal is a joke. Corner and a free header five yards out. So if you concede goals that like you've got no chance. We've got tighten that up.
"Passing wise? We're supposed to be a passing team. We just kept giving the ball away. Too many players didn't turn up.
"It's never nice to get beaten. We've got to roll our sleeves up now and go to Blackpool on Tuesday and get a result. Sometimes you learn more when you lose than when you win."
