Burton Albion suffered their heaviest Championship defeat as a dominant Leeds United side thrashed them 5-0 at Elland Road.
The hosts were in control of proceedings from Oliver Langford's first whistle to his last, with a debut double for Pierre-Michel Lassoga the highlight for them.
Had it not been for a couple of timely blocks, Albion's goal difference may have taken even more of a hit.
With the ins and outs of the transfer window done, Nigel Clough made five changes from the side that drew 1-1 at home to Sheffield Wednesday before the international break.
Those switches included immediate starts for deadline-day signings John Brayford and Jamie Allen, with the former at right-back in a 4-5-1 and Allen as part of the central midfield trio.
He started alongside former Rochdale teammate Matty Lund and Kyle McFadzean, kept in that position to add solidity to Burton's midfield.
But it is hard to imagine that any amount of tactical positioning could have kept Leeds at bay in what was a thoroughly dominant first half.
Had it not been for a superb Brayford block off the line to deny Lasogga - a stop like so many he made last season - it would have been 1-0 inside 10 minutes.
Instead, it took until the 20th minute for the Whites to push themselves in front.
Some of their movement and passing was as eye-catching as anything Burton will have seen so far this term, and Eunan O'Kane's defence-splitting pass for Lasogga came under that bracket, the Leeds forward latching onto it before sliding a first-time finish past Stephen Bywater.
Kalvin Phillips then made it 2-0 by curling home a delightful strike from the righthand corner of the Burton box as Clough's side tried to withstand wave after wave of Leeds pressure, before Pablo Hernandez stretched the hosts' lead even further from the penalty spot just before the break.
And there was no let-up from Thomas Christiansen's unbeaten side after the break, as much as Burton would have hoped for a chance to get a foothold.
The first 15 minutes of the second half belonged to Kemar Roofe, who pushed Albion well and truly out of contention with a fine goal and assist.
His strike saw him curl home from 20 yards after running at the retreating Ben Turner, before he got in behind the Brewers defence and enjoyed far too much freedom before lobbing a cross onto the head of Lasogga for the debutant's second of the afternoon.
It took Clough's men until well past the hour mark to register their first shot, Allen blazing over from Lund's lay-back 25 yards out.
That statistic in itself sums up the gulf in the class on the day.
As it was, the Brewers would come no closer to a consolation, while Leeds were unable to add to their efforts.
The damage had well and truly been done in the opening hour, though, with Burton needing to cast such a humbling defeat from their minds quickly ahead of Tuesday's trip to Norwich City.
