The Seagulls supremo revealed how he worked out a Whites side that fell apart after half an hour on Friday night to end up with a season's worst defeat.
But Hughton clearly remembers a gritty Rangers draw against his team at Loftus Road in December - especially as Hoops came back from 2-0 down to forge a final 2-2 result.
The Albion man in charge also mentioned one Ranger clearly in the forefront of his mind.
Hughton said: "They are certainly more settled now. Jimmy (Floyd Hasselbaink, head coach) has kept the same system in the way the team has played.
"(Sebastian) Polter is playing far more regular now and they have got that little more stability in their team now.
"They are certainly more resolute and are on the back of a result at the weekend at Cardiff – and that is a good result against a team pushing for play-offs.
"We saw at Loftus Road the quality they also have. For them it would have been a good result having been 2-0 down."
When Fulham were 2-0 down on Friday, it was over and out. Hughton says his homework paid off after Whites dominated the first 30 minutes.
The Albion boss said: "Fulham played a system with two deeper midfielders which enables them to have a lot of possession.
"Our job was to try and be patient, press within the shape. It’s when you go away from that shape that they can cause you problems.
"Apart from that, it was about waiting for that break and about being better once we got the ball."
