A number of Sunderland fans are calling on the club's board to appoint Roy Keane as their new manager.
The Black Cats are searching for a new manager after sacking Lee Johnson following an embarrassing 6-0 defeat at Bolton.
They are currently third in League One and two points behind leaders Rotherham United.
But Johnson was dismissed after Sunderland recorded just one win from their last five games.
Keane managed Sunderland between August 2006 and December 2008, winning the Championship in his first season in charge before leaving following a fallout with the hierarchy.
And many Sunderland fans would like to see the Manchester United legend return to the club as boss.
One tweeted: "I always tell people the exact same think. Roy Keane was an absolute force of nature at Sunderland. Something about him just fit perfectly with the ethos of the club. Maybe he’s just the level of crazy you need to succeed here."
Another said: "Roy Keane would be what we need always feel we are good going forward but can’t defend to save our lives."
Someone else commented: "Get Roy Keane back at Sunderland."
One other tweet read: "Sunderland’s next manager absolutely fucking screams of Roy Keane surely."
Keane went on to take charge of Ipswich Town after leaving Sunderland but has not been in management since 2011, although he has worked as an assistant to Martin O'Neill at the Republic of Ireland and Nottingham Forest and to Paul Lambert at Aston Villa.
But Keane revealed last year that he has had interviews for jobs.
He told Gary Neville on Sky Sports’ series The Overlap: “I’ve had interviews, I had an interview recently.
“I spoke to a Championship club about three months ago. It was very casual, it was at my house – a chat with the chairman.
“And to be fair, he was straight up, he went: ‘Listen, we just want somebody who can come in and win football matches.’
“That was fine with me, I didn’t have to break down styles of play. And I think if you’re winning matches, people don’t then question, ‘What’s your style of play?’
“You just bounce into the next match, don’t you? And we did it as players.”
Keane previously revealed that his departure from Sunderland “still saddens” him.
"I still think I should be manager of Sunderland,” he added. “I really liked the club, and I liked the people."
