Aquilani spent last season on loan at Juventus but was not offered a permanent stay despite making 33 Serie A appearances for the Turin giants.
The 26-year-old was linked with a move to AC Milan and Napoli this summer but confirmed earlier this month he will play for the Reds next season.
Italian job: Aquilani wanted to remain in his native Italy
'Alberto's thoughts were to stay in Italy, but this was not possible,' Aquilani's agent Franco Zavaglia said to Radio Sportiva. 'He had a positive season (at Juventus).
'I don't know if in this market there will be the possibility for him to return to Italy and it's a shame that our players are forced to go and play away from Italy.'
Failure to launch: Aquilani's Anfield career is yet to take off
However, he added: 'Liverpool are an important club and they have overcome the problems they had a year ago with the previous owners so they can win the Premier League.'
Liverpool signed Aquilani for a reported fee of ?20million from Roma in 2009 and he is under contract with the Reds until June 2014.
