Huge ask - even if we win 19 and draw 4 - they would have to drop 19 points from now for us to win it on goal difference. Lets say we beat them at ours that is 16 points from 22 games.
Also look at it this ways - the above from us would get us 93 points.
For them to get 93 they need 17 wins 2 draws and 4 defeats or 16 wins 5 draws 2 defeats.
Highly unlikely i am afraid that they will drop that many or we will get that many.
But if it happened i would masturbate in just my coat and a city scarf right outside the Kop on a match day.
You are probably right on the presumption that they won't get significant injuries or that they won't collapse for some unpredictable reason. As things stand, we have virtually no room for error. We can afford 2 draws from the last 23 games or one defeat.
