Two seasons ago Pontypool won the WRU National Championship and Narberth were runners-up.
Last season was a repeat of the previous season.
This season Pontypool are currently top and Narberth second.
So, on Saturday at Pontypool Park, there will be the mouth-watering clash of the two best teams in the Championship.
The final game last season saw Pontypool gain a very important 27-20 win at Lewis Lloyd Ground as it gave Pooler the perfect 22 wins from 22 matches.
Earlier last season Pooler overcame the Otters 29-0 in their home fixture.
Pontypool have won the last six matches against their west Wales rivals.
