When Jose Mourinho takes his side to Old Trafford on Monday night, it will rekindle memories of classic clashes between English giants Manchester United and Chelsea from yesteryear.
In the last 10 years, since Roman Abramovich became the owner of Chelsea, matches between the two clubs have tended to be tense affairs – with a few exceptions, of course.
Nevertheless, in this look back at five of the most memorable matches between the two clubs, three of the games took place in the last five years, while the other two occurred in the pre-Abramovich era.
So, let's take a trip down memory lane, and whet the appetite ahead of Monday night's mouth-watering clash at Old Trafford.
5. Manchester United 3-3 Chelsea (September 2000, Premier League)
Claudio Ranieri's first match in charge of Chelsea was certainly a memorable one.
The Blues took the lead courtesy of an early Jimmy Floyd Hasselbaink strike, but the hosts scored three goals before half-time to seemingly wrap up the points for the reigning champions.
Not so. Tore Andre Flo netted just before the break to make it 3-2 at the interval, while the tall Norwegian striker completed his brace with 20 minutes remaining to earn the west Londoners a hard-fought point.
4. Chelsea 3-5 Manchester United (January 1998, FA Cup)
Ah, the third round of the FA Cup - that weekend in early January which produces magical moments, year in and year out.
Back in January 1998, United and Chelsea played out an eight-goal thriller at Stamford Bridge, a match which proved that, in football, momentum is everything.
David Beckham – remember him? – scored twice in the first half, before Andy Cole made it 3-0 to the visitors at half time. Cole then completed his brace in the second half before Teddy Sheringham made it 5-0 with little more than 15 minutes left on the clock.
However, Chelsea produced a spirited mini fight-back, with Graeme le Saux scoring a fantastic lob over Peter Schmeichel before Gianluca Vialli netted twice.
Who knows what would have happened with a bit more stoppage time?
3. Chelsea 5-4 Manchester United (October 2012, League Cup)
A fabulously bonkers match from last season's Capital One Cup, which saw Chelsea eventually run out 5-4 winners.
Admittedly, neither manager fielded a full-strength team, but that didn't stop it unfolding into a League Cup classic.
It was a pulsating encounter which featured nine goals, eight different scorers, three penalties, nine yellow cards, last-gasp strikes – the lot.
2. Chelsea 3-3 Manchester United (February 2012, Premier League)
This was one of Sir Alex Ferguson's last classic comebacks of his glittering 26-year career as Manchester United manager.
A Jonny Evans own goal, plus strikes from Juan Mata and David Luiz five minutes after half time appeared to have fired Chelsea into an unassailable lead.
However, comeback kings United never know when they're beaten, and so it proved in February 2012, when two Wayne Rooney penalties and a late Javier Hernandez header earned a memorable point for Fergie's men.
1. Manchester United 1-1 Chelsea, 6-5 on pens (May 2008, Champions League final)
One of the most dramatic Champions League finals of recent years, played on a rainy Wednesday night in Moscow, Chelsea came within a penalty-kick of being crowned European champions for the first time in their history.
Cristiano Ronaldo opened the scoring with a fine header before Frank Lampard equalised just before half time.
Following a goalless second half, both Lampard and Didier Drogba hit the woodwork for Chelsea, but the real drama was yet to unfold.
John Terry had the chance to win the Champions League trophy with one spot kick. However, as we all know, the Chelsea skipper slipped and hit the post, allowing United back in with a shout.
The Red Devils' name was effectively on the trophy from that point, and wild celebrations were sparked when Edwin van der Sar saved Nicolas Anelka's penalty, as United celebrated their third European triumph.
