Drama has never been far away from the Italian during a colourful career that began with Lazio nearly 30 years ago, and he wrote another chapter of his story today when he released a statement saying he had resigned from his post.
The 44-year-old, who played for Celtic in 1996-7, scoring 15 goals in 37 appearances, guided the Robins to promotion in his first season in charge last term.
But he has grown increasingly tetchy about the boardroom goings-on at the County Ground and tonight decided enough was enough.
Town have been the subject of a takeover bid for some time and Di Canio, who claimed to have first tendered his resignation last Tuesday, had pledged to stay if the deal was ratified by the Football League by 5pm today.
No transaction was confirmed, though, and the former West Ham striker issued a statement through his agent, Phil Spencer, confirming he had quit.
"Last Tuesday, 12th February, I formally confirmed my resignation as manager of Swindon Town Football Club with immediate effect," said Di Canio.
"There have been a number of broken promises made by the club over the time that I have been manager of Swindon Town.
"Despite these problems, I have delivered everything and more that was asked of me, by achieving promotion last year as champions and competing this season for promotion to the Championship and being just three points from top place a year earlier than expected.
"I did not resign immediately, nor publicise my resignation after I had formally confirmed it as I did not want to jeopardise the negotiations for the sale of the club and I wanted to listen to what the proposed new owners plans were.
"Following discussions, my representatives put forward a proposal that would secure my future at the club until at least the end of the season and quite possibly beyond as well.
"This proposal actually reduced the club's contractual liabilities to me in the interest of saving Swindon Town FC. At a meeting last Friday the proposed new owners accepted and said they were very happy with the new terms.
"I entered into a temporary arrangement with the proposed new owners to continue in my role as manager but all this was agreed subject to Football League approval for the purchase of the club being granted by 5:00pm on Monday 18th February.
"At the time of issuing this statement, I have had no further contact from the proposed new owners and I have been told that unfortunately Football League approval has not been granted yet and therefore my temporary arrangement has ended and my resignation stands."
When asked to clarify Di Canio's resignation, a Swindon spokesman told Press Association Sport they were unable to expand on the statement.
One of Di Canio's bugbears was the sale of Matt Ritchie to Bournemouth without his consent, a move indicative of the simmering tensions in Wiltshire.
Di Canio's success in the dugout has shocked some, with a number of observers considering him too hot-headed to manage a team.
As a player he courted controversy by pushing referee Paul Alcock to the ground while at Sheffield Wednesday, while he also had a number of disciplinary issues when at Celtic.
He joined Celtic in 1996 after an 11-year spell in his homeland where he struggled to establish himself with the likes of Lazio, his boyhood team, and AC Milan.
He left Wednesday for West Ham where he became a legend in the eyes of the United fans, scoring one of the Premier League's most memorable goals against Wimbledon.
After parting company with the Hammers he went to Charlton, before an emotional return to Lazio, although his time there was stained by his support of fascist movements and his association with the club's Ultras.
He retired from playing in 2008 and leaves Swindon sixth in League One, three points off top spot.
