John O'Shea believes making the Stadium of Light a fortress will be a key factor in Sunderland retaining their top-flight status.
The Black Cats have been poor on home soil this season and that form continued on Saturday with a last-gasp defeat to relegation rivals Wigan.
Steve Bruce's side have only won one of their seven league games to date and the north east side now sit just two points above the drop zone.
Former Manchester United defender O'Shea is not used to a relegation dogfight, but he knows their upcoming games with Wolves and Blackburn are crucial fixtures.
"You see the attendances we are getting, the fans coming to support us and especially at home, we haven't had as many wins as we would have liked," said O'Shea.
"That's something we have got to change very quickly because if you want to stay in the Premier League, your home form is supposed to be key.
"We are going to have to definitely change that. We are away next week, but we have got a good enough belief to get three points at Wolves and then get three points at home to Blackburn.
"But that's easier said than done."
