Di Canio warns Sunderland they're not yet safe
Di Canio refused to concede that one more victory would be enough to secure the club's top-flight status.
He said: "I don't think it's enough. Every weekend, our prediction changes. If Wigan can win against Swansea, they are 34, three points from the main group close to them on 37 with four games to go.
"I don't know, it depends. If you get three points against Aston Villa, it can probably be enough, 40, 41; if you lose against Aston Villa or Stoke and then you beat Southampton, maybe it's not enough.
"I don't know. If we win the direct conflict (with Villa), 40, 41 can be enough, otherwise it's difficult."
