IN THE end, Fulham's need was clearly more urgent than QPR's, as all pre-match predictions of a tight and cagey affair melted away in the freakish October heat.
It was a triumph for Andrew Johnson in particular – the striker (pictured) who netted his first Premier League goals of the season with a blistering hat-trick to give him more ammunition in contract talks which have so far come to nothing.
Danny Murphy got in on the act with a spot kick and Clint Dempsey made it five by finishing off one of many sweeping moves full of pace which Rangers, missing the injured Danny Gabbidon, seemed incapable of defending.
Bobby Zamora – seldom far from the action with his smart touches and link-ups with Johnson – deservedly rifled in the sixth.
It equalled the club's best win in the Premier League.
For Rangers, it was a truly awful day – a first defeat since the start of the Tony Fernandes era - and for them, it was hardly worth a decade-long wait for the revival of this particular west London derby.
They were a goal down with the game barely 90 seconds old and struggled to draw any positives from a humbling afternoon. Perhaps the return of Jamie Mackie after a long recovery from a broken leg was a close as they came to taking something from their humbling visit to the Cottage.
A first win in nine games in midweek against Odense in the Europa League was very welcome for Fulham, but boss Martin Jol wanted three Premier League points more than anything.
The prospect of going into a two-week international break with no win to his new club's name in the league after seven games did not bear thinking about. He got his wish in spades.
Fulham fans were pretty keen to see their team make a statement too – Rangers threatening to steal some of their thunder after an unbroken decade as, if nothing else, Chelsea's main west London satellite.
Rangers, beaten twice by Fulham when the teams last met in the Whites' promotion year, were caught cold at the start when Johnson finally transferred his Europa League potency to the league and Murphy's penalty after 20 minutes put the hosts firmly in the box-seat.
But such was the home side's dominance, that the damage to a passive QPR could and should have been even more severe during that time.
Dempsey fluffed an open goal by slamming a shot against Bradley Orr, with a badly exposed Paddy Kenny beaten, and Johnson hitting a superb volley narrowly wide after Zamora had nodded down a Steve Sidwell pass.
“Are you Brentford in disguise?” the Hammersmith End mocked. There was more to come.
Johnson, a scorer of a double in midweek, scored the first goal when he pounced after Kenny could only palm away a low shot from Mousa Dembele. It was his first in the league.
The penalty arose when Johnson, now looking as sharp as a tack, nipped in ahead of Fitz Hall to invite a trip from Kenny on the edge of the area.
It was no real surprise when Johnson made it 3-0 after 38 minutes. The striker turned in a left foot shot in from close range after Zamora had powered a low ball across the face of the area.
Three up at the break, the lead was doubled by the 74 th minute. First Johnson completed his hat-trick tucking home a quickly-taken free-kick on the hour, then Dempsey powered home after Johnson's low cross from the left had been touched on by Zamora on 65.
Nine minutes later and Rangers fatally stood off Zamora, allowing the striker to bury a shot past a seemingly unsighted Kenny. For all the cover he got, Kenny just as well have been blindfolded from the start. There is much for Neil Warnock to think about now after such a reality-check.
