Roy Keane has admitted that he would still like "another go" at club management, despite acknowledging the lack of stability on the domestic scene.
Since November 2013, Keane has been employed as assistant to Republic of Ireland manager Martin O'Neill and the pair recently extended their contracts with the Green Army.
However, Keane - a former boss of Sunderland and Ipswich Town - has revealed that he would consider a return to club management should an offer come his way.
At a press conference, the 46-year-old told reporters: "There's huge pressure on managers. You look at good managers going in and out of doors and it has you scratching your head.
"I used to try to figure it out before, certain managers not getting enough time at a club, but I've stopped trying to do that, it just doesn't make sense.
"It's kind of a mad industry we're in at the moment. If you can get a bit of stability in your job, fantastic, but at the moment, particularly at club level, it's probably non-existent. Despite everything I said, I'd like another go, yes."
Keane's last senior role came with Ipswich, with the Manchester United legend leaving Portman Road in January 2011.
