New Sunderland manager Roy Keane sees no reason why he can't enjoy a successful working relationship with Black Cats chairman Niall Quinn.
The pair have had their problems in the past, particularly in the fall-out following Keane's spat with then Republic of Ireland boss Mick McCarthy four years ago in the build-up to the World Cup finals in Japan and South Korea.
"I think my relationship with Niall will be fine, I really do," said the former Manchester United and Celtic star. "A lot of people make a big issue of it. We sorted it out in the summer, whether or not I took the job.
"People have impressions of me. I've had differences with thousands of people over the years. I care, that's the type of character I am.
"I've played under some great managers, some good managers and some not so good managers.
"We met three months ago and I spoke to Niall, but at the time my priority was to sit my 'A' coaching badge. He got back in touch last Monday when I was in Portugal.
"My attitude was that I would wait a bit longer. Then I thought what am I waiting for?.
"The challenge is there. Sunderland is a big club with a beautiful stadium, a good fan base and I thought why not?"
