Brentford boss Uwe Rosler admitted his side were near faultless as they comfortably saw off Preston 3-1 to heap more misery on North End manager Graham Westley.
Shaleum Logan's early header was added to by a Clayton Donaldson strike either side of half-time, one a penalty after the striker was felled by Daniel Devine and the other a header, as Brentford eased to victory.
Paul Parry's late first-half penalty, following Harlee Dean's foul on Graham Cummins, was no more than consolation for the hosts, who have won just twice in 14 games since Westley took over.
"In the first half we were almost perfect," Rosler said. "We played a compact game with a high line and came here to compete.
"Preston have a direct, aggressive style of play but we took the physical challenge to them and football-wise we were better too.
"We countered and passed the ball well and, aside from the penalty situation, the two centre-halves did very, very well, so it was an all-round satisfying performance from us.
"Preston didn't have one attempt on goal throughout the second half and when they did cross the ball in we dealt with it easily.
"We were here to play football. Sam Saunders found very good positions and Clayton Donaldson was completely unstoppable.
"The back four couldn't deal with him at all and the players around him brought him into the game well and that was the recipe for success."
