The England international snubbed Chelsea in favour of a move to Anfield on deadline day.
Oxlade-Chamberlain, 24, rejected a bumper contract offer from Arsenal this summer and informed Arsene Wenger he wanted to quit the Gunners.
The former Arsenal star has been used as a winger, and attacking midfielder and in the middle of the park during his time in London.
And Oxlade-Chamberlain says he has told Reds boss Jurgen Klopp he wants to be an attacking midfielder at Liverpool.
“I’ve spoke about this for about six years - my whole career - where I'm going to be playing or where I'd like to play,” he told Liverpool’s website.
“I just say I'd like to be an attacking midfielder.
“I've spoke to the manager about this, there's going to be a lot of positions [available] in this team: up-front, because the wingers play a bit more inside, or the midfield.
“I wouldn't like to put a label on it at this stage, I need to get a feel for how the team plays and obviously it's for the manager to decide.
“But ultimately, I just want to be able to be an attacking influence and have that effect further up the pitch; whether that's from an attacking midfield position or one of the wider positions coming in, I'm not too fussed.”
