Milan announced on Friday it had acquired Aquilani on loan with the right to purchase his full contract. He has signed with Liverpool to June 2014.
Milan is prepared to pay Aquilani 2 million ($2.9 million) this season and 2.5 million ($3.6 million) the next two seasons—less than he was earning at Liverpool.
The 27-year-old Aquilani began his career with his hometown club Roma, then transferred to Liverpool for the 2009-10 season. He spent last season on loan at Juventus.
