West Ham United return to Barclays Premier League action on Wednesday night when they journey across London to play Chelsea at Stamford Bridge.
The two sides may be battling it out at different ends of the league table, but the Hammers have plenty of away victories over the Blues to look back on as they try and create more history.
Here, whufc.com takes a look at six away wins over the west Londoners.
Chelsea 2-3 West Ham United
28 September 2002
Paolo Di Canio took centre-stage on the occasion of West Ham United's most recent victory at Stamford Bridge - and their long-awaited first win of the 2002/03 Premier League season.
After Jermain Defoe had equalised Jimmy Floyd Hasselbaink's penalty opener before half-time, the Italian forward took control of proceedings after the interval. On 48 minutes, Di Canio allowed a throw-in to bounce before controlling on his thigh and sending a rasping volley past a stunned Carlo Cudicini in the Chelsea goal.
Future Hammers manager Gianfranco Zola then made his own case for goal of the match by curling an exquisite free-kick high into David James' net with 16 minutes remaining. Di Canio would have the last laugh, however, firing a low shot between Cudicini and his near post after William Gallas's clearance had ricocheted off Defoe's head.

13 March 1999
West Ham were enjoying a season spent almost entirely in the top eight when they took to Stamford Bridge and emerged victorious thanks to a single goal.
Paul Kitson was the hero for the Hammers, replacing Paolo Di Canio in the starting XI and making his mark with the game's solitary goal as he forced the ball home after Marc-Vivien Foe's flick-on.
The victory helped the east Londoners to finish just two places behind their city rivals in fifth, representing a great season for Harry Redknapp's team.

Chelsea 1-2 West Ham United
17 February 1996
West Ham United arrived at Stamford Bridge having been humbled 3-0 at Division One side Grimsby Town in an FA Cup fourth-round replay in their previous fixture - missing out on a potential fifth-round meeting with Chelsea. However, Harry Redknapp's Hammers turned things around by pulling off a stunning Premier League victory over the Blues in west London.
With Julian Dicks playing in a central defensive role, West Ham stormed to their fourth consecutive Premier League win, despite falling behind to Gavin Peacock's 13th-minute opener.
Dicks himself headed in the equaliser just after the hour mark before midfielder Danny Williamson completed the turnaround with 18 minutes remaining, silencing the majority of the 25,252-strong crowd inside the three-sided Stamford Bridge.

2 October 1994
West Ham United lifted some of their early season gloom as they overcame the Blues at Stamford Bridge to record just their second league win of the season. The Hammers entered the match with low morale, having lost four of their opening seven league games coupled with a League Cup loss to Third Division Walsall.
The lowly Hammers gave Chelsea a day to forget with goals from Martin Allen and John Moncur snatching a well-earned first away win of the season.
Later in the month more success over the Blues followed in the shape of a third round League Cup win which came courtesy of a Don Hutchinson goal.

Chelsea 0-4 West Ham United
29 March 1986
Easter Saturday 1986 is a date that will be forever remembered by West Ham United supporters. On a muddy quagmire of a pitch, the Hammers turned on the style to rip Chelsea to shreds at Stamford Bridge.
Alan Devonshire put West Ham in front on 23 minutes before the Hammers truly turned on the style after half-time. Tony Cottee scored twice in the space of nine minutes - the first to complete a sweeping counter-attack led by George Parris and the second a clinical finish from Frank McAvennie's square pass - before McAvennie himself completed the rout by smashing Cottee's mis-hit high past goalkeeper Tony Godden.
Victory took West Ham up to sixth in the table and continued a fine second half to the season that ended with John Lyall's side finishing in a club-record high finish of third in Division One.
Chelsea 0-3 West Ham United
28 November 1964
Six months on from lifting the FA Cup at Wembley for the first time in the Club's history, Ron Greenwood's West Ham United chalked up another memorable victory. Having defeated Arsenal and Leeds United in their previous two league fixtures and scored a 2-0 win over Sparta Prague in the European Cup Winners' Cup second round first leg in midweek, the Hammers travelled to Chelsea full of confidence.
Alan Sealey, who would score both goals in West Ham's Cup Winners' Cup final victory over TSV 1860 Munich the following May, opened the scoring at Stamford Bridge after just eight minutes. Martin Peters and Geoff Hurst then made the game safe.
Amazingly, West Ham's win meant they had scored at least one goal in every one of their 19 league matches played thus far in the 1964/65 season. The Hammers would complete the double over Chelsea the following April, but the Blues would knock the holders out of the FA Cup at the fourth round stage in January 1965.
