"Fortunately all of the teams we wanted to lose, lost, so the loss doesn't really add to our concerns except in the sense we've one less week to get out of trouble," Plunkett said.

There is no let up for the squad next Sunday when they play fifth-placed Forrest Hill Milford at Becroft Park. Plunkett tried in vain to get the game rescheduled for Saturday so two of North Force's key players could participate in the match but he said the competition's bosses wouldn't go for it.
"It's a real shame, especially when other clubs are given dispensation to postpone games at the eleventh hour because their players are supposedly busy milking," he said.
Plunkett is annoyed that relegation rivals Ngaruawahia were allowed to postpone two of their games earlier this season rather than default when they were unable to raise a team while North Force's rescheduling request - made well ahead of time - was dismissed by the league's management.
"When things are this tight it always sticks in your throat that one team gets the rub of the green and the other doesn't," he said.
