David Artell said his team must learn to 'see out' games after two late goals consigned them to a 3-2 defeat at Wycombe Wanderers.
The manager was left scratching his head after the Alex allowed the hosts to strike in the 88th and 90th minutes to wipe out a Chris Dagnall double.
it was Crewe's fourth consecutive defeat and sixth in the last seven.
Manager Artell said: "We have got to learn to see the game out but it was cruel on us because they have scored two screamers to win it.
"I felt it was undeserved. The better side lost, but that can happen in football. We are on the wrong end of a defeat but I thought it was unjust.
"With the exception of the result, I thought we were terrific. But we cannot keep on losing games of football and the players are hurting.

Nathan Tyson gave Wycombe Wanderers a dramatic late and utterly deserved victory with a rip-roaring 3-2 victory over Crewe Alexandra.
Tyson smashed home an unstoppable shot from the edge of the box on 90 minutes after being put through by a glorious ball from Ebere Eze.
Michael Harriman equalised two minutes earlier when he smashed the ball home from 20 yards thanks to Tyson's cross to give Wycombe a lifeline.
It had all looked good early when Wanderers went 1-0 up on 27 minutes thanks to Craig Mackail-Smith's second goal in as many games, when he converted from Adebayo Akinfenwa's flick on.
However, four minutes before half time, Crewe skipper Chris Dagnall stabbed home from six yards after Michael Raynes knocked down Perry Ng's cross.
Then completely against the run of play on 64 minutes, Dagnall met Chris Porter's flick-on and calmly slotted the ball past Scott Brown for a barely deserved lead.
