Manuel Pellegrini's side lifted their first trophy of the campaign after beating Sunderland on Sunday, but which players were named in our best side from the competition?
The tournament is always a chance for fringe players, as well as stars from the lower divisions, to impress and battle against clubs from the Premier League. Find out who made it into our Capital One Cup Team of the Tournament below.
Costel Pantilimon has provided strong competition for Joe Hart's place at Manchester City this season but the 27-year-old was a regular fixture in Manuel Pellegrini's side for the Capital One Cup.
Pantilimon missed just one match of City's campaign and conceded just one goal - Fabio Borini's opener in the final - during the tournament.
Phil Bardsley missed the third round and quarter-final but was an influential figure when he featured for Sunderland during the latter stages of the tournament. The Scot scored the opener in the 2-1 win over Southampton in the fourth round and also netted the vital equaliser in the semi-final second leg against Manchester United at Old Trafford.
Two dependable figures at the heart of the Black Cats' defence were key during their run to the Capital One Cup final. Wes Brown and John O'Shea played a vital part in helping Gus Poyet's men to dump Chelsea and Manchester United out of the competition, while the pair were excellent at Wembley, despite the defeat to Manchester City.
At left-back, Aleksandar Kolarov may have started the final for Manchester City but Gael Clichy was a solid performer in the build-up to the clash at Wembley and the Frenchman helped his side secure three clean sheets along the way.
Lloyd Dyer made a significant contribution to Leicester City's Capital One Cup campaign, including three goals from midfield, until Nigel Pearson's men were dumped out by eventual winners Manchester City at the quarter-final stage.
Ki Sung-Yueng missed Sunderland's second-round win over MK Dons but was an ever-present for the remainder of the tournament. The South Korean displayed an excellent range of passing and oozed composure in central midfield, plus his 90th-minute strike memorably dumped Chelsea out of the competition in the quarter-finals.
Yaya Toure featured only sporadically for Manchester City in the Capital One Cup this season but the Ivorian's contribution was huge. A goal to put Pellegrini's men four goals ahead at home to Wigan in the third round may not have made the biggest impact but his stunning effort to level the score at Wembley, after City went behind early, was the catalyst for his side's second-half comeback.
Lee Tomlin's Capital One Cup tournament may have ended by the third-round stage with Peterborough but the forward netted twice in the 5-1 win over Colchester in the first round and followed up his double with a hat-trick in the next round against Reading.
Manchester City's Edin Dzeko and Alvaro Negredo share the tournament's Golden Boot with six goals each and both played a pivotal role in firing Pellegrini to his first trophy since taking charge at the Etihad Stadium.
