After Sunderland's 0-0 draw with West Brom on Saturday afternoon, a simple fact became apparent about the Black Cats' top-flight status.
Win against Norwich City and Sam Allardyce's men can stay up. Three points would take Sunderland to within just one of Norwich with a game in hand.
But defeat to the Canaries would almost certainly relegate Allardyce's side.
Yes, they would still have an extra game over Norwich but the psychological blow would be huge.
Sunderland are playing well under Big Sam but they have drawn too many games they should have won. And that's put huge emphasis one of their upcoming Premier League clashes - against Norwich.
Alex Neil's men have now won two in a row and all the momentum is with them. But a win against the Canaries could do wonders for Sunderland. It all comes down to the weekend after next, once the Wearside outfit have played Leicester and lock horns with their relegation rivals.
