he added that it is unlikely he will take a similar position to those he held at the Stadium of Light with any club.
"Sunderland is the only club I've done more than play for," said Quinn, who scored 78 goals in six years as a City player.
"The club was in pretty bad shape when I went in there so I felt as if I had to do it.
"It wasn't a chosen career path, it arrived at me. I got stuck in and did it.
"It can be unforgiving and pretty thankless at times because you can have a great week off the pitch, and then something goes wrong on a Saturday, you get well beaten, and the confidence in you has waned.
He added: "I had six great years at Sunderland doing that but it was a natural end for me. I'm not quite sure what the next step is."
