Ross McCormack smashed a first-half hat-trick as Fulham sank Nottingham Forest 3-2 at Craven Cottage.
The Scottish striker took his goal tally for the season to 10 with three long-range strikes to crank the pressure back up on Forest boss Stuart Pearce.
The visitors threatened a comeback when Henri Lansbury scored either side of half-time, and would have dragged themselves level but for a glaring miss by top scorer Britt Assombalonga.
But Fulham held out for a victory which was a far cry from when the teams met at the City Ground in mid-September, with Forest top of the table and Fulham rock bottom.
Following a late win at rivals Derby at the weekend, Nottingham Forest have hit the ground with a bump, conceding three first-half goals at Fulham.

The Football League have announced that three Championship clubs have been placed under a transfer embargo.
Leeds United, Blackburn Rovers and Nottingham Forest have all suffered the same punishment.
