Sunderland are believed to be weighing up a move to bring Keane back to the club for a second spell as manager, with bookies slicing their odds on the Irishman making a return to the Stadium of Light.
Keane has previously suggested that his explosive reputation could count against him as he aims to resume a management career that has stalled since he was sacked as Ipswich manager in January 2011.
Now the Daily Mail are reporting that Sunderland are weighing up a move to hire Keane for a second time, after his first spell at the club brought instant success as he guided the club to Premier League promotion in 2007.
Sunderland's move to sack Lee Johnson after last weekend's 6-0 drubbing at Bolton sparked suggestions that 50-year-old Keane could be a contender for the role.
Now, rumours are sweeping through the football grapevine suggesting Keane is a candidate the Sunderland board are keen to speak to as they look to find a new boss.
Keane signed David Meyler for Sunderland during his first spell in charge at the club and the former Ireland midfielder believes his old boss deserves another crack in management.
"Sometimes the media portray an image of someone and it sticks, but it's only when you get to know someone that you appreciate there is a different side to someone like Roy Keane," Meyler told sundayworld.com.
"The perception we have of people is not always right and that's certainly the case with Roy.
"We all know he doesn't hide his feelings and some people don't like that side of him, but now they are seeing Roy for who he really is.
"You look at the interview Roy did with Gary Neville or the little videos he does with Micah Richards, and you might have a different view of him. That shows the side of Roy Keane I have known in my time with him at Sunderland and then with Ireland.
"There is a human being there, and he is not just this fella who is always angry. He is a great personality.
"People might have a different view of Keane now. I hope they do.
"They might have thought they knew Roy, but then they see him chatting in a different way about all aspects of his life, and they understand there is a man who has a lot more to him than some people believe.
"And who knows, it might help him get back into management if people realise he is not as bad as he has been made out to be down the years."
Sunderland owner Kyril Louis-Dreyfus and sporting director Kristjaan Speakman will lead the search for the new manager, with Keane still a popular figure with the club's fans after his first spell at the club.
