Reds CEO Grant Mayer confirmed the news on the Soccer On 531 radio programme on Saturday morning.

Mayer said that new Adelaide coach Marco Kurz wanted to bring in his own playmaker from overseas.

He also revealed that 33-year-old Carrusca and his representatives deemed the offer tabled by United as not good enough to re-sign.

The future of the out-of-contract Carrusca has been in limbo throughout the off-season, with the appointment of Kurz ultimately deciding his fate.

Adelaide has already seen Eugene Galekovic, Dylan McGowan, Kim Jae-Sung, George Mells, Jesse Makarounas, John Hall and Kim Jae-Sung depart this off-season.

The Reds have added goalkeeper Paul Izzo while Australia youth international George Blackwood is set to sign too.

Carrusca became a fan favourite at Coopers Stadium, having joined Adelaide in 2012 following stints with Galatasaray, Estudiantes and San Martín de San Juan.

The attacking midfielder made more than 100 appearances for the Reds, scoring 25 goals.

Carrusca is a three-time PFA A-League Team of the Season selection and won the club's Player's Player of the Year in 2013/14.
