Keane wants to see bar raised
Irishman 'very happy' in job on Wearside
Roy Keane insists he is happy to stay as Sunderland manager, but wants the club to match his ambitions.
The former Manchester United captain took charge at the Stadium of Light in August 2006 and led the club to promotion to the Premier League in his first season.
He is edging closer to keeping Sunderland in the top flight this term, but only has a further season left on his contract.
Keane intimated he would be willing to agree a new deal on Wearside and hopes the club's owners will help him to fulfil his aspirations for the Black Cats.
The Irishman told reporters: "I've got another year on my contract and am I happy at Sunderland? Very happy. But will I be here tomorrow? I don't know. I might die tonight.
Proper football club
"It's OK having a three-year deal, but I'll be into my third year next year.
"I understand the business side of it, I've got to manage the club upwards as well as downwards and people need to know where they stand.
"If we can stabilise, then people keep asking me: 'Do I want to carry the challenge forward?'
"But I have to ask the people who own the club the same question: 'Are we prepared to go to the next bar?' It works both ways.
"If I was ever to leave Sunderland then where would I go? There's not many bigger challenges. Sunderland are a proper football club."
