Manchester United v Chelsea - Past meetings
Manchester United manager Jose Mourinho will face up to his former club Chelsea again on Sunday in the latest chapter of one of English football's most storied rivalries.
Here Press Association Sport takes a look at some of the more memorable previous encounters between the two sides.
Dec 1905, Division Two: Man United 0 Chelsea 0
The first meeting between the two clubs attracted a remarkable crowd of 67,000 on Christmas Day in 1905. Played at United's then home of Venue Bank Street in Clayton, the game finished goalless. United would go on to finish second behind champions Bristol City and gain promotion, with Chelsea, in their first season in existence, nine points behind in third.
Jan 1998, FA Cup: Chelsea 3 Man United 5
Manchester United looked to be cruising to victory until the home side threatened a dramatic comeback. Two goals each from David Beckham and Andy Cole, and one for Teddy Sheringham, sent United into a 5-0 lead with 16 minutes remaining. But Chelsea rallied with goals from Graeme Le Saux and Gianluca Vialli, before Vialli's second three minutes from time set United's nerves jangling.
Apr 2006: Premier League: Chelsea 3 Man United 0
Mourinho's Chelsea guaranteed their second straight Premier League title with a 3-0 win at Stamford Bridge. William Gallas, Joe Cole and Ricardo Carvalho scored for the home side while the sight of Wayne Rooney being carried off on a stretcher sent the game into panic stations with the World Cup in Germany fast approaching.
May 2008: Champions League final: Man United 1 Chelsea 1 (6-5 pens)
United emerged successful from the first all-English Champions League final in Moscow. Cristiano Ronaldo opened the scoring for United before Frank Lampard equalised just before half-time. Didier Drogba was sent off in extra time and in a thrilling penalty shoot-out John Terry missed the chance to seal victory for Chelsea before Edwin van der Sar saved from Nicolas Anelka to seal United's win.
Oct 2016, Premier League: Chelsea 4 Man United 0
Mourinho clashed with Blues boss Antonio Conte and was serenaded with chants of "You're not special any more" as his United side crashed to an humiliating 4-0 defeat. Pedro opened the scoring after just 30 seconds and further goals from Gary Cahill, Eden Hazard and N'Golo Kante contributed to Mourinho's thoroughly miserable Stamford Bridge return.
