<text>  Roy Keane has the broad shoulders and mental toughness required to manage Manchester United, according to his former Old Trafford engine room colleague, Paul Ince. Ince, 47, a double-winner with Keane at United in 1994, on Thursday hailed the Irish assistant manager as a leader of men. I speak to Roy and he does want to get back in to management but at the right establishment, with the right project. Roy Keane is not a number two, Roy Keane is a leader of men, said Ince. Roy Keane has the mental toughness required to manage Manchester United, says Paul Ince . Ince slides in for a tackle during Uniteds game against Sheffield Wednesday in 1992 . And if the right thing job comes along then Im sure he will get back into it management. Keane was last in charge at Ipswich over four years ago but even so Ince is convinced the 43-year-old will be a top, top manager and could even return to the front-line at United. To be Man United manager you need broad shoulders and take a lot of criticism. Roy has broad shoulders and he is mentally tough. Things dont affect him, said Ince. He has a poker face, doesnt show if things are affecting him, and there is no reason why Roy couldnt go back to Manchester United as manager. You cannot lose people like him from the game, warned Ince. He knows so much about football, no matter what your cup of tea is. Ince is convinced Keane, who was last in charge of Ipswich four years ago, will be a top, top manager Some people love him, some people hate him. You always try to guess what Keanies like but he does not let people into his head. Hes got a vast knowledge of football and he sets the highest standards. You dont get the players anymore with Roys standards, he added. You do hear people say Roy rules by fear. Maybe, thats Roy and the way he is. Maybe, thats how he feels he can be a success in what he does and he did it at Sunderland. Roy Keane has an ego. We all had egos at Man United because thats what made us who we were, he added. Ince rejected any suggestion that Ryan Giggs left might succeed Louis van Gaal as United boss . Ince rejected any suggestion that Ryan Giggs might succeed Louis Van Gaal at United. No chance, he said. Youve got to go to a club that you can learn from and get experience. Hes not ready for Man United. Ince didnt rule out Keane succeeding Martin ONeill as Irish manager. Maybe he Keane thinks that when Martins done, then hes the next one to step up. Thats the logic I see in it, he said. International football is hard because its once every month or two months. I think Keanie would like to be on the training ground every day, cautioned Ince.
