Bottom line is we HAVE to beat Barrow to have any chance of staying in this league. Assume we beat them, that would mean we were then 5 points to the good with a further 6 matches still available to each of us.
Assuming we can't win any of those six then :-
Barrow would have to win three of their six to pip us by one point, or win two and draw one to do it on points difference.
