The Blues looked dead and buried after just 10 minutes in the original tie, but a stirring second half performance saw them come back from two goals down to earn a replay on their own turf.
Alex Ferguson admitted that his side were fortunate not to lose at Old Trafford, and Chelsea are now favourites to progress to the semi-finals at odds of 6/4 (2.50) with Bet365.
The Red Devils' 2-0 sixth round replay win back in 2003 was the hosts' last FA Cup defeat at Stamford Bridge, and you can get odds of 7/4 (2.75) on them emerging victorious again, as they managed in October's Premier League fixture.
Alternatively, there are odds of 5/2 (3.50) available for these sides to take the game into extra-time by recording a draw after 90 minutes.
The 2-2 draw at Old Trafford was just the latest in a long line of entertaining clashes between these rivals, who have provided 16 goals in their three encounters this season alone.
There have been at least three goals scored in 12 of the last 14 matches between this pair, and in every one of the last seven, so odds of 8/13 (1.62) look like money for old rope on over 2.5 going in here.
That bet would also have paid out in seven of Chelsea’s last eight and six of United’s last seven FA Cup ties.
A key factor in the Blues' comeback at Old Trafford was Benitez's decision to replace Frank Lampard with John Obi Mikel just after half-time, as this freed up Ramires to put his boundless energy to constructive use going forward.
The Spanish tactician was rewarded when the midfielder grabbed a timely equaliser -his third goal in the last three games against Ferguson's men.
Considering the Brazilian's prolific record against this opposition, it is well worth having a wager on him hitting the back of the net on Monday, at generous 5/1 (6.00) odds.
