The Italian international failed to adapt to English football.

The deal will see the winger head back to Italy after three difficult seasons as a Sunderland player – which saw him start just 18 Premier League games and spend last season on loan at Serie A side Bologna.
Giaccherini was a shock coup for Sunderland back in 2013. He arrived from Juventus for a fee reported by The Mirror to be in the £6.5 million region – so they are losing a considerable amount in this exit.

The Italian also clearly has talent.
He recently starred at Euro 2016 but has never managed to adapt sufficiently to the physical side of the Premier League.
The general consensus from Sunderland fans on Twitter is that the player had to go, considering his inability to adapt to the Premier League style.
However, others are also shocked that Sunderland could not have used his recent good form for Italy to their advantage, and tried to recoup more of the transfer fee for the player.
Here is some reaction from Twitter…
Emanuele Giaccherini has left Sunderland. He fell through a crack in the pavement— ALS: SAFC FANZINE (@ALS_Fanzine) July 16, 2016
Shame about Giaccherini departing. Clearly has the talent but simply not cut out for the physical aspect of the Premier League #safc— David Nunn (@DavidNunn73) July 16, 2016
Personally think Giaccherini was incredibly talented, just lacked the physique to perform regularly in the Premier League #SAFC— james (@Sunlunfan) July 16, 2016
Only Sunderland would pay over 20 million pounds for Fletcher and Giaccherini and let them go for free and 2 million #SAFC— Mykell Beal (@MykellBeal) July 16, 2016
