Manchester United are set for a blockbuster showdown against Chelsea in the Premier League at Stamford Bridge on Sunday evening.
It is a clash between two English heavyweights battling to secure UEFA Champions League football with a top-five finish.
The two sides have played several memorable games over the years.
Here we revisit four of their unforgettable and entertaining Premier League battles that have left fans on the edge of their seats.
The game that ended one of the most memorable streaks in Premier League history.
Jose Mourinho-led Chelsea were on a mesmerising 40-match unbeaten run.
Darren Fletcher headed United to victory and became the unlikely hero. United defended desperately for the majority of the game, with goalkeeper Edwin van der Sar also bravely denying Frank Lampard.
This victory was also crucial as it came on the back of a miserable week for United after Roy Keane castigated his team-mates in a MUTV interview.
His comments were so explosive that Sir Alex Ferguson and chief executive David Gill immediately decided to scrap the tape.
The Blues were desperate for revenge, and they got that in the ultimate manner by securing the Premier League title with a victory over United at Stamford Bridge.
William Gallas set the tone with an early strike. Joe Cole tricked his way past Rio Ferdinand and Nemanja Vidic to score a sensational goal.
A right-footed shot from Ricardo Carvalho found the back of the net, allowing the home crowd to burst into celebrations.
Winning the coveted league title twice in two seasons established Mourinho as a legend in England.
A Jonny Evans own goal separated the two sides at the interval. Juan Mata and David Luiz made it 3-0 with only 40 minutes remaining in the contest.
Most teams would have folded but the Red Devils did the exact opposite.
Wayne Rooney dragged United back into the contest with two nerveless penalties.
Javier Hernandez scored the ultimate equaliser before David de Gea made a flying save right at the death.
This seven-goal thriller remains fresh in the memory of fans.
Chelsea raced to a 2-0 lead before United turned the game on its head. Alejandro Garnacho and Bruno Fernandes scored to cap off a thrilling first half.
Garnacho put United ahead with a simple header after Antony delivered an outrageous trivela cross.
A perfect comeback story was written in destiny for Chelsea.
Diogo Dalot conceded a penalty in the 99th minute, allowing Palmer to restore parity.
United had barely recovered from the shock when Chelsea caught them sleeping from a quickly taken short corner in the 101st minute.
A wicked deflection wrong-footed Andre Onana, with Palmer completing his hat-trick and condemning the Red Devils to their first league loss to Chelsea in seven years.
