The Italian international arrived at Anfield following a £17 million move from Roma but has been used sparingly so far this term despite recovering from injury.
Aquilani was labelled as the ideal replacement to fill the midfield void vacated by Xabi Alonso following the Spaniard’s move to Real Madrid.
However, the 25-year-old had to wait until late-October to be handed his debut in a League Cup tie at Arsenal and is yet to be given his first start in a Liverpool shirt.
And his father insists Aquilani is not struggling for fitness, as believed, and says the Reds’ summer signing is eager to be involved.
“Alberto’s available to play and has been for more than a month,” he said in The Guardian.
“He feels good and the injury has cleared up, and now the only way he can get truly fit is to play more and more minutes.”
Aquilani’s father revealed his son is enjoying life in England but is clueless as to why the Liverpool manager continues to ignore him from his first-team plans in the Premier League.
“He is really happy in Liverpool, he has settled in really well,” he added.
“He’s getting to grips with the language, which was a problem at first, and he is always surrounded by friends, family and his fiancé.
“He is desperate to get his career in England up and running. He has been very frustrated, first at being injured, then at not being chosen to play for so long. Obviously he’s not happy at waiting for such a long time to get involved with the team.
“I don’t know of any special motivation for Benitez in not playing him.
