Here are the permutations
Burnley have to beat Man utd away otherwise they can't finish above us.
If Luton lose or draw and Everton win we are safe
If Forrest lose and Everton win we are safe.
If Everton Draw than we can't be mathematically safe but if Luton lost it would become 9 points with 3 to play, so they would need a huge huge swing in goal difference
Even if we lost it would only be a an awful weekend if two or all win won.
As even if we lost and only Forrest or Luton win then the other two would have to win every match and Everton would have to lose every game to be relegated.
