Luton boss Graeme Jones said he was “embarrassed” by his side’s performance after they slumped to a 7-0 defeat at Brentford.
Jones apologised to the supporters who travelled to watch the ruthless Bees register their biggest win in 25 years.
“Everything that could go wrong did go wrong. We were fragile defensively and attacked with no intensity. We just collapsed and I have told the players that,” said Jones.
Josh Dasilva’s hat-trick followed strikes from Bryan Mbeumo, Ollie Watkins and Mathias Jensen, with Said Benrahma completing the rout in the second half.
The Bees are now up to seventh after back-to-back wins at Griffin Park for the first time this season.
A sixth defeat in seven games, meanwhile, leaves Luton a point above the Championship drop zone.
Jones added: “I was so embarrassed with that performance. I feel sorry for our supporters. They travelled in numbers and I need to apologise for that performance.
“We have to make sure this is never repeated again. They have to man up and get on with it; they have to take responsibility for their performance.
“We seem to be taking two steps forward and 10 steps back. But we’re a small club in a big league so we will take a few on the chin, dust ourselves down and come back.”
The Hatters have now leaked 40 goals – more than any other Championship side – and their defensive frailties again reared their head six minutes in when Mbeumo poked home after a poor backpass from Dan Potts evaded goalkeeper James Shea.
Brentford’s top scorer Watkins then made it 12 goals for the season just before the half-hour mark with a tap-in following Dasilva’s pass.
Four minutes later, Watkins turned provider and found Jensen in the box, with Luton defenders allowing the Dane to spin and stroke the ball into the bottom corner.
Dasilva cut inside from the right and curled in with his left foot from 20 yards, then made it five by squeezing home from a tight angle in first-half stoppage time.
A tired visiting defence conceded two penalties in the second half, the first slotted in by Benrahma before Dasilva completed his hat-trick by rifling low past Shea.
The last time Brentford managed as big a win was at home to Plymouth Argyle in the then Second Division in 1994, when the Bees also hit seven without reply.
Brentford head coach Thomas Frank:
“That first half was one of the best first halves in many years, not just because it was 5-0 but because we created lots of chances, scored goals and gave nothing away.
“In the second half I was happy that even at five, six and seven we were still showing concentration and work rate to keep the clean sheet. That is the mark of a top, top team.
“It’s not easy when the game is dead very early like it was, but we restricted them to one shot on goal and I think we were very professional in the second half.”
