“We have come a long way in such a short time in our efforts to restore lost pride to our national game and team, and this (PMs XIII match) is only part of the process. It will be a huge match for us, and I am sure Mal Meninga and Michael Marum will do everything they can to ensure they are at their best come Sunday.
