Ahead of Sunday's mouthwatering League Cup final clash at Wembley, we count down City's best moments in the competition...
20. Doyle's delight, 1970
Just five minutes had passed when West Brom had broken the deadlock at Wembley.
Jeffrey Astle's effort gave the Baggies an early advantage - but City produced an excellent response and Mike Doyle's strike sent the game into extra time.
Glyn Pardoe netted the winner and the Blues lifted their second trophy in nine days, having emerged victorious in the European Cup Winners' Cup final against Gornik Zabrze in Austria.
19. Seventh Heaven, 2014
Championship side Sheffield Wednesday strolled into the Etihad Stadium dressing rooms at half-time holding City to a 0-0 draw and presumably pleased with their display.
However, a stunning seven-goal blitz from the Blues in the second half stunned the Owls and sent the hosts through to the next round in emphatic fashion.
Frank Lampard proved the star of the show, netting a brace and assisting two, as the cup holders hit the Wembley trail once more.
18. Capital gains, 1994
The Blues headed to Loftus Road with an unbeaten record against Queens Park Rangers in cup competition, and with the Hoops fielding a much-changed side, few could have predicted what was to unfold over the next 90 minutes.
The visitors suffered a nightmare start, as Kevin Gallen struck for the hosts after just 13 seconds, but a stunning volley from Nicky Summerbee levelled the score.
Trevor Sinclair then handed Rangers the lead once more, but a Keith Curle penalty and sublime volleys from Peter Beagrie and Steve Lomas turned the game on its head.
Gary Penrice headed in consolation with three minutes remaining set up a nervy finish but the visitors held out for the victory.
17. Dream debut, 2015
City's place in the next round of the Capital One Cup had been all but guaranteed well before youngster Manu Garcia emerged from the bench to make his first senior appearance at the Etihad Stadium.
The Blues has already claimed a 4-0 lead over Crystal Palace, and the Spaniard put the icing on the proverbial cake with a goal on his home debut in injury time.
He had fellow starlet Kelechi Iheanacho to thank for the assist, as the Nigerian played the perfect through-ball into Garcia's feet - and the attacking midfielder controlled well before slotting underneath goalkeeper Wayne Hennessey.
16. Top four, 1976
Middlesbrough arrived at Maine Road looking to preserve their slender advantage from the semi-final first-leg.
Instead, they met a rampant City side who netted four goals to book their place at Wembley.
Ged Keegan opened the scoring with a header before Alan Oakes drilled home the second.
Peter Barnes and Joe Royle then capitalised on a pair of defensive mistakes to slot home and seal a memorable triumph.
15. Defeating the Pilgrims, 1974
City hosted Plymouth in the semi-final second leg, with the aggregate score level.
Tommy Booth's header had cancelled out Steve Davey's effort in in the away leg and a couple of goals from some legends-to-be would settle the tie.
Francis Lee and Colin Bell found the net at Maine Road to hand the Blues a 3-1 lead and set up a clash against Wolves at Wembley.
14. King Henry II, 1979
City's hopes of reaching the next round looked all but over as the second leg encounter with Sheffield Wednesday reached its final moments.
Following a 1-1 draw in Yorkshire, in which Colin Viljoen scored, the Owls took the lead at Maine Road and looked to be sailing through - but all was not lost.
Two Tony Henry strikes in the dying minutes clinched an incredible comeback to ensure the Blues' progression.
13. Paying the penalty, 1981
With a 2-0 lead from the first leg at Maine Road, thanks to Asa Hartford's strike and an own goal, City looked to be in a commanding position heading into their second leg tie at Stoke.
However, the Potters earned themselves a victory of the same margin and so a penalty shoot-out was required to decide the winner.
Incredibly, both sides found themselves all square after eight penalties each and the ninth would be decisive - the Blues netted theirs, but Stoke did not and the visitors would be the ones to progress.
12. Six and the City, 2014
Manuel Pellegrini's men placed more than a foot into the final of the Capital One Cup with a thumping 6-0 demolition of West Ham.
Three goals in each half, including a hat-trick for 'the Beast' Alvaro Negredo, ensured the second leg would prove a mere formality.
The pick of the bunch arrived courtesy of the Spaniard, who volleyed home Toure's lofted pass with aplomb to open the scoring.
11. Kun down the Gunners, 2011
The Blues made the trip to North London having failed to register an away win against the Gunners since 1975.
The visitors left it late to clinch a place in the semi-finals, as Sergio Aguero completed a wonderful counter-attacking move with seven minutes of normal time remaining.
Typically, the Argentine executed the perfect first-time finish to send the travelling fans delirious and City into the last four.
