Italian has found it difficult to adjust at Anfield.
The Italian underwent ankle surgery just prior to making the switch and has struggled for fitness.
His situation has not been helped by the Reds' disappointing season so far.
"Ideally, I would have been able to start playing in a team that was winning matches," he told The Daily Mirror.
"But instead, by the time I was fit, the team was going through a difficult period.
"That made the transition to English football a lot harder. As a foreign player, moving to a new country with different team-mates, it would have been easier for me if I was starting my Liverpool career in a winning team.
"It hasn't been that way, so the pressure has been on me to produce performances straight away - when I have played though I know I can do a lot, lot better."
Aquilani is confident that he will improve as he finds his match fitness, and is looking forward to playing in a full-strength Liverpool side when key men return from injury.
"At the moment I am still regaining my fitness after a long time away from football and it will take me time to get back to a level I am happy with - but I don't think I'm that far away," he added.
"The manager has explained to me in detail what he wants me to do for the team.
"When every player is fit, including me, I think it will bring the best out of me, and the fans will see the real player.
"I am happy at Liverpool and am already completely settled.
"It is clear it is a family club and I am grateful for the way I have been treated - and I now want to repay that kindness."Click here to follow the Goal.com Twitter feed
