John O'Shea has confirmed that senior Sunderland players went to the club's hierarchy to voice concerns over Paolo Di Canio.
The Italian parted ways with the Stadium of Light outfit following a 3-0 defeat away to West Brom on September 21, which left the club rooted to the bottom of the table without a league victory this season.
Rumours soon circulated that the former Swindon Town manager's reign ended due to a backlash from squad members over his management of the team.
And O'Shea has vindicated that speculation, but called for everyone to move on from the incident.
When asked whether players had approached senior club officials to raise concerns over Di Canio, O'Shea told The Shields Gazette: "That was obviously done. But we have to move on now.
"Because of the position we're in in the league, we can't keep going back to it. We've got some difficult months ahead.
"Whoever comes in, whether it's Bally (Kevin Ball) or a new manager, we've got tough times ahead.
"We have to stick together and if we keep going back to it, it'll soon be too hard to pull back from where we are."
Caretaker manager Ball saw his team put in a much-improved performance in Sunday's 3-1 home defeat to Liverpool.
And O'Shea revealed that the side would welcome the appointment of Ball on a permanent basis.
He added: "Without a doubt, he's made an impact. If It does happen the players would be very happy.
"But we will wait and see what the club decides."
