Sunderland chairman Niall Quinn is hoping to tie manager Roy Keane down to a new long-term contract at the end of the season.
Keane's first season as a Premier League manager looks like being a successful one with the Black Cats currently seven points clear of the relegation zone.
The former Manchester United and Republic of Ireland midfielder has just one-year left on his contract at the Stadium of Light, but Quinn is hoping to agree a new deal with his former international team-mate when the current campaign draws to a close.
However, Quinn is aware that the ambitious Keane will one day decide to leave Wearside with speculation continuing to suggest he will replace Sir Alex Ferguson when he finally decides to leave Manchester United.
"There will be top clubs who have looked at what is happening at Sunderland," he told The Guardian.
"As the thing gets better and better you can see somebody coming in for our manager.
"There's no point saying it's not going to happen - somebody will try to take Roy from us at some point."
Meanwhile, Quinn is predicting a second summer of investment in the club's playing staff.
"The summer will be the time for Roy to set out his requirements," he added.
"I don't think for one minute that personal finances will come into it. I'm sure he'll want to talk about the structure and the ambition.
"When we sit down it will be a case of discussing where we're going and what the next three years and beyond hold for us."
