The Italy international has drawn a line under a forgettable time at the Wearside club and returned to his homeland.
Sunderland have confirmed on their official website that they have sent Italy international winger Emanuele Giaccherini back to his homeland on loan, with the 30-year-old joining Bologna for the 2015-16 campaign.
The tricky wideman never really adapted to life in the Premier League, with glimpses of his ability but not enough consistency to warrant a regular starting berth for the Wearside club.
The versatile midfielder was seen as something of transfer coup when he arrived at the Stadium of Light in 2013, given that he was signed from Italian champions Juventus.
Fresh from featuring in the Confederations Cup when he signed, Giaccherini was adjudged as a staple of the Azzurri squad and has in total amassed 21 caps for his country.
However, the former Cesena man only made 43 appearances for the Black Cats over the 24 months at the club, hitting the back of the net five times.
Although Giaccherini leave Sunderland having failed to make a major impact, there is a feeling that the Italian could have been a much better performer if he had been given more chances to play and managed correctly.
