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. Playing in his preferred role of central midfield, he delivered one of the finest performances of his short Liverpool career.
Oxlade-Chamberlain left north London for Merseyside in the closing hours of the summer transfer window.
"Since he's come to Liverpool, after a slow start, he's gathering momentum at a crucial part of the season and he's becoming a very, very important player to this Liverpool side at the moment", he explained.
"That game will mean just as much if not more for our fans".
It was all about Oxlade-Chamberlain's effort, and Liverpool supporters began thanking Arsenal for the midfielder.
Oxlade-Chamberlain is set to play a key part in the coming week for the Reds, alongside Gini Wijnaldum and James Milner, who will be Liverpool's only senior midfielders for next week's clash with Manchester City in the second leg.
Klopp theorised: "We had a lot of talks".
"Sometimes it's only about changing the circumstances."

"I think they were both treading water at Arsenal, it's as simple as that", Redknapp said on Sky Sports.
"He was ready to work hard and there is a different style of football".
"It was never bad, only because Ox as a kid was an outstanding talent that people said it was not exactly what we had imagined, but he is an outstanding talent still and there is still a lot of things to improve - no problem with that".
"We can't make him quicker - we don't have to".
"I could have been better on the ball and there are areas I need to improve on and can improve on".
"The manager (Klopp) has been pushing me all season and shouting at me for not taking the game by the scruff of the neck at times and providing those kinds of moments, being the one shooting and making the difference", Oxlade-Chamberlain admitted. With his confidence surely at an all time high after the night of his life at Anfield, Oxlade-Chamberlain now has an excellent chance to leave any regrets from his time at Arsenal behind.
