Cas have to be favs especially at home and have been the better team this season, but a win wouldn't and shouldn't be out of the question, as we've shown against Saints twice - yes I know we just lost away but we really shouldn't have.
I hope with just 2 games left this season that we don't go through the motions, which tbf they haven't done so far and it'd be nice to nail that 5th spot again.
