Alex Oxlade-Chamberlain has impressed for Liverpool this season.
Oxlade-Chamberlain, who made it 2-0 with a long-range strike beyond City goalkeeper Ederson, admitted the home support was "unbelievable" - and not just during the game.
Towards the end of his last season with Arsenal, the England worldwide struggled to find his best form and Arsene Wenger was blamed for the player's poor performances.
The Reds became the first team to record two victories over Pep Guardiola's Premier League leaders this term as goals from Mohamed Salah, Sadio Mane and Oxlade-Chamberlain handed Jurgen Klopp's men a commanding 3-0 lead in the quarter final tie.
The pair, who are both graduates of the Southampton academy, spent six years together as teammates at the Emirates, playing a combined total of 595 games and scoring 128 goals during their respective time at the club.

The Reds' fans thanked Arsene Wenger-led Arsenal for selling the Englishman to Liverpool.
The truth is that, as with so much else at Arsenal, Oxlade-Chamberlain's failure to reach his potential is a source of much confusion and wistfulness.
'Being in a different place, sometimes, can be better but only if you are aware of your problems.
I'm really pleased for the OX and many people must now understand player development has unfortunately stopped at Arsenal! "I have to improve to get to where I want to get and to be as good as I hope to be so I keep working on it".
"He was not coming here and saying 'come on, make the best of me, use me in the best way". "It got us going and it would probably shake anyone up so you have to give fans credit for that".
'He's an outstanding talent still, still a lot of things to improve, no problem with that'.
"We can't make him quicker - we don't have to". "The further you go the better the teams you play against and you don't get many opportunities so you have to be clinical".
