West Ham were en route to promotion when they made the long journey to Sunderland in December 2004.
It was a successful trip as Alan Pardew's side notched twice without reply to take all three points.
A red card to the hosts' Steven Caldwell helped West Ham on their way, and they took the lead on 59 minutes through Marlon Harewood.
Teddy Sheringham's final minute goal sealed the victory.

22 March 2003
West Ham moved out of the bottom three for the first time in four months with a much needed victory at home to Sunderland.
The attacking trio of Jermain Defoe, Frederic Kanoute and Les Ferdinand gave the Mackems defence the run around as the Hammers took all three points.
Defoe got the first midway through the opening period when he swivelled and placed a shot past Thomas Sorensen. Kanoute replaced the injured Ferdinand at half-time and put the game to bed with a cool finish.

A brace from Mark Robson inspired West Ham to a thumping win over Sunderland in 1992.
There were also goals for Alvin Martin, Martin Allen, Trevor Morley and Kevin Keen as the Wearsiders left east London empty handed.
The emphatic win sent the Hammers up to fifth in the table in a season which they went onto finish second in the league, gaining promotion to the Premier League.

Eamonn Dolan was the catalyst for a big home win over the Mackems as the Hammers continued their good early season form.
A crowd of just over 20,000 turned up to see Dolan net twice, half of his tally for the season, with three of his teammates also getting in on the act.
Kevin Keen, Martin Allen and Stuart Slater scored a goal apiece to round off a miserable day for their visitors from the North East.

Geoff Hurst ran riot against The Black Cats, netting an incredible double hat-trick as the Hammers recorded a huge win.
Hurst stole the show with six goals of his own but Trevor Brooking and Bobby Moore also managed to get their names on the scoresheet.
The striker's haul helped to take him to an impressive 31 goals by the end of the season as he helped fire West Ham to an eighth place finish whilst Sunderland were well below them finishing 17th.
