Dejected Crewe boss Steve Davis blamed his side's lack of a cutting edge for their 5-0 mauling at promotion-chasing Brentford.
The Alex collapsed in a miserable second half after Brentford made their possession count within 30 seconds of the restart.
Two goals from former Crewe striker Clayton Donaldson eased the Bees to their second five-goal haul against Crewe in as many seasons.
Marcello Trotta, who opened the scoring before the break, and George Saville also got on the scoresheet for the Londoners, but it was Adam Forshaw's 46th-minute strike that turned the game.
Davis said: "We coped very well with them in the first 44 minutes but their goals either side of half time changed things.
"We stifled them for most of the first half and had some nice passages of play, but we didn't really create anything.
"We've been punished from the kick-off of the second half which is pretty poor, but in reality what is costing us is not scoring goals.
"We need to have a cutting edge and be meaner at the other end. The players have to stand up and show what they can do. They did it last season so they can do it again.
"We will go away and work hard to put things right, but we know where we need to improve and that will be a priority in the week ahead.
"That wasn't good enough, but I was heartened by the first-half performance and that is something for us to build on."
