C... h... e... l... s... e... a... the letters in the name of Sunday's visitors to Old Trafford provide plenty of cues - excuses, if you like - to show some classic action from United's games against them over the years.
Watch our free video and you'll see some memorable clips from European and domestic contests with the West London club, including a landmark goal scored by one of United's greatest-ever players and a red card that helped to ruin a Russian's night.
