"It was an awesome atmosphere, the best I've ever played in", said the £40 million summer acquisition from Arsenal. It definitely shows why I wanted to come here.
Liverpool will head to the Etihad stadium on 10th April for the return fixture knowing that if they bag a vital away goal then the tie will all but over, and a place in the semi finals will beckon.
"I think back to a few years ago when he got in the England team, looked like he was going to go to the World Cup, got injured. It got us going and it would probably shake anyone up so you have to give fans credit for that".
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. My game I wasn't too happy with.
"At times it has gone against me because I can be hard on myself and beat myself up a bit", he said.
"He [the referee] gave me a booking, but I was a bit disappointed because I hadn't conceded many fouls during the game. It was always "I could do more" or 'I could have done something more".
Oxlade-Chamberlain has been around for so long - he is now in his 10th season as a professional - that it is easy to forget he is still very young but it is clear he is exhausted of being talked about in terms of potential and, like the side he represents, is in a hurry to make a lasting impression. He also claimed Jürgen Klopp's team were ideally suited to the Champions League and the latter stages in particular.
"We definitely have qualities that are suited to this competition", he added. "[But] all players can improve".
"You don't get many opportunities so you have to be clinical and the three boys up front this season have managed to stand out in how clinical they have been".
"We had a lot of talks and Oxlade loved Arsene Wenger, really".
"Now, he's flying, you can see the training at Liverpool that they must do".
