A point for Sunderland means they are safe as long as Wigan don't beat Arsenal AND Villa (alternatively one of Norwich or Newcastle pick up less than 2 points).
A point for us means we only need at most a draw against Stoke to be safe. And we can lose* to Stoke if Wigan fail to beat Arsenal and Villa, OR Villa lose against Chelsea, OR Newcastle fail to win one of their last 2 matches, OR Norwich fail to win one of their last 2 matches, OR Sunderland lose to Spurs, OR we lose by only 1 goal to Stoke and Sunderland fail to beat Spurs.
This has 0-0 written all over it.
