It would be a sensational return to the Premier League for the 24-year-old, who left Manchester City in 2013.
Balotelli has been involved in a series of scrapes during his career to date, especially during his time in the Premier League.
On the field, he was sent off for Manchester City against Arsenal in 2012 in a defeat that almost derailed their title charge.
And off the pitch, there was the notorious incident when Balotelli set off fireworks in his house, leading to him revealing the famous ‘Why Always Me?’ T-shirt when he scored in the Manchester derby at Old Trafford in 2011.
He also had a set-to with City manager Roberto Mancini on the training ground, and a scrap with Jerome Boateng.
The striker’s agent Mino Raiola flew to England on Wednesday to try to thrash out a deal.
Since returning to Italy, he has scored 30 goals in 54 games, the same amount he scored for City in 80 games.
And it is easy to forget that he has already won four titles in two countries, a Champions League and the FA Cup and Coppa Italia by the age of 24.
