Di Canio, who oversaw Swindon's promotion to the third tier of English football in his first season in charge, is unhappy with conditions at the club, who are in financial strife.
The Italian said, in a statement released to the Swindon Advertiser, that he would have already left the club were it not for the Robins fans and players.
“It is with great regret that I issue this statement," Di Canio said, "but unfortunately, the events of the last few days have left me with no alternative other than to consider my position and explain the reasons why. As ever, the great fans of Swindon Town Football Club deserve to know the truth.
“Without going into too much detail, our preparations for the game at Leyton Orient on Tuesday were severely undermined by an administrator for the Club actively offering to sell our entire playing staff without any reference to me and contrary to the terms of my contract.
"[...] A statement issued by the Club yesterday stated that they were committed to achieving Championship football next season. I have to question how this can possibly be achieved in the light of the events I have brought to your attention.
“I have worked so hard for the Club and made many sacrifices because I wanted to achieve something special. The players and my staff have been fantastic to me and the statistics prove that my way of managing, playing football and working is successful.
"With the club selling one of our best players behind my back and continually making promises that are broken, I feel at this moment that my job is not just impossible but is untenable. Of course I shall remain professional and continue to achieve the best I can, but under these circumstances it is not easy.
“If it wasn’t for the players and fans of Swindon Town, I would have walked away from this club a long time ago. I didn’t because I was given repeated assurances that the project to achieve success was always in place and I wanted to deliver this for the players, staff and most of all, the fans of this great Club.
"Despite being linked with a number of more high profile managerial jobs, they have never interested me. Now however I am forced to consider my future as I don’t know how I can continue to work in this environment.
“Too many questions remain unanswered.
“The future is clouded with uncertainty.
“At this moment of time my future remains unclear.”
