Tough one to call this but I'm going for Saints to have enough attacking weapons in the locker to break down the excellent Wigan defence.
I think I can speak for every fan in hoping that they smash ten bells out of each other so that the losers will be physically incapable of putting up a fight next week.

Should be a belting match tho and hopefully a bumper crowd.
If the fans can't turn up tonight for a local derby with a GF place at stake then the game really is in a sorry state.
