Man City knock out holders Liverpool in League Cup thriller
This last-16 clash marked the return to competitive action of two of English football's heavyweights following the World Cup break and their latest encounter was a high-octane affair.
Premier League champions City twice led through Erling Haaland and Riyad Mahrez, only for Liverpool to waste little time in drawing level thanks to goals from Fabio Carvalho and Mohamed Salah.
But after Ake made it 3-2 shortly before the hour mark, the visitors were unable to fashion a third equaliser.
City manager Pep Guardiola named six World Cup players in his starting XI.
Ake, Manuel Akanji, Aymeric Laporte, Rodri, Kevin De Bruyne and Ilkay Gundogan were all involved from the kick-off.
Liverpool boss Jurgen Klopp, whose side pipped Chelsea 11-10 in a marathon penalty shoot-out at Wembley in February as the Reds won the League Cup for a record ninth time, also named a strong side.
The German's forward line included Salah, making his first appearance in the League Cup outside of finals since October 2020, Darwin Nunez and Carvalho.
Liverpool captain Jordan Henderson was included on the bench but fellow England international Trent Alexander-Arnold was not involved at all, with Netherlands defender Virgil van Dijk also omitted after his World Cup stint.
Haaland and Cole Palmer both missed the target when well-placed to score early on but it was not long before the Norway star made amends.
Haaland, seemingly given a free run against Liverpool's defence, turned in De Bruyne's near-post cross in the 10th minute after getting in front of Joe Gomez to score his 24th goal of the season.
Liverpool, however, were level within 10 minutes when Carvalho finished from a James Milner cross after the former City midfielder was allowed too much room in the penalty area.
The visitors made two changes at half-time, Fabinho and Alex Oxlade-Chamberlain coming on for novice midfielder Stefan Bajcetic and Carvalho.
But Liverpool fell behind again before either of the two substitutes could get into the game.
Only 76 seconds into the second half Mahrez fired home from the right side of the penalty area following a cross by Rodri.
City's lead, however, evaporated just over a minute later as Nunez sprinted past Laporte down the left, with Salah making light of a mediocre centre to draw Liverpool level at 2-2.
But a rollercoaster contest then saw City go ahead for the third time when, after a quickly-taken corner, Ake powered in a 58th-minute header from a superb pinpoint cross by the outstanding De Bruyne.
Oxlade-Chamberlain went down in the penalty after a collision with Ake in the 69th minute but David Coote denied the Reds a spot-kick and, with VAR not in use, the referee's decision stood.
Liverpool, however, had an excellent chance to make it 3-3 when a superb ball from Naby Keita left the onside Nunez free down the right touchline.
But after sprinting clear of the City defence, Nunez, albeit from an acute angle, pulled his shot wide of the far post.
