Roy Keane has spent much of his post-playing career making his feelings known about Manchester United

Roy Keane has regularly voiced his opinions about Manchester United throughout his post-playing days, yet a return to the manager's office at Old Trafford seems ever more unlikely. The former captain's name has surfaced as a possible contender amidst mounting speculation over Michael Carrick's position.

Nevertheless, despite his iconic status at the club and his reputation for insisting on excellence, Keane has strongly suggested he harbours minimal interest in resuming managerial duties.

United's difficulties have intensified, with a solitary win from their first nine Premier League matches leaving them stranded in 17th position. A remarkable 3-2 comeback victory against Roma in the Champions League on Tuesday finally halted a nine-match winless run, though it has scarcely dampened the mounting scrutiny of Carrick.

Sunday's journey to Aston Villa may consequently prove pivotal. It represents United's last fixture before the international interval, during which senior figures are anticipated to review Carrick's situation and determine whether his tenure should be brought to a close.

Several high-profile managers have been linked with the position, including Eddie Howe, Julian Nagelsmann, Antonio Conte and Unai Emery, reports the Mirror.

Yet former Premier League striker Djibril Cisse reckons Keane would prove a thrilling choice, citing his iconic standing at Old Trafford, commanding presence and deep-rooted connection with the club.

Cisse, who worked under Keane during his time at Sunderland, told Mr Gamble: "It would be another club legend coming back. If it were him [David Beckham buying out Sir Jim Ratcliffe] and Roy Keane, that would be amazing.

"Keane has the weight of experience and history. He is a strong personality and he's an icon of the club. He wore the armband for so many years during United's glory days, so bringing him back would be a really good thing.

"I really enjoyed working with him because he didn't judge me on what he'd heard or what people might say about my character. He trusted me, it worked very well, and I was very disappointed when he left. He's a coach I loved working with and whom I respect enormously."

However, Keane has now provided a somewhat contrasting view regarding the prospect of managing a side once more. Speaking on the Stick to Football podcast, the former Ireland assistant indicated he possessed the attributes to excel as a manager, while admitting the pressures and unpredictability of the role no longer hold much attraction for him.

When host Gary Neville observed that Keane 'has lived what Carrick's going through right now', Keane responded: "I feel for them.

"These last few years [of prioritising TV punditry over coaching] ... there's no going back now," Keane continued. "There's definitely part of me over the last few years that thinks I should still be a manager somewhere. I still feel I could have been a really good manager.

"When you're in that managerial role, you're thinking two or three bad results and you could be out the door... that's a tough rollercoaster. I don't miss being on that rollercoaster, I just have this feeling that I could have been a really good manager."

Keane initially entered management in 2006, soon after concluding his distinguished playing days, when he took charge at Sunderland. His influence was instant, guiding the Black Cats from the Championship into the Premier League in his first season before securing their top-flight status the year after.

However, his tenure in the North East eventually concluded during his third year, with Sunderland languishing near the bottom of the table. Keane then moved to Ipswich Town, though his second spell in the dugout proved comparatively brief, with the Irishman departing after less than two years without achieving the Premier League promotion the club desired.

He progressively transitioned into coaching positions instead of assuming managerial duties, working as assistant manager alongside Martin O'Neill with Ireland, Aston Villa and Nottingham Forest. Beyond the pitch, Keane was simultaneously building a prominent profile as a television figure.

Following his initial appearances on ITV, he transferred to Sky Sports, where his standing as one of football's most captivating analysts has steadily strengthened. His forthright opinions, cutting remarks and characteristically deadpan wit have established him as an enormously well-liked figure on television, though his readiness to offer unflinchingly frank evaluations has naturally sparked debate.
