Friday sees rematches of the 1991 and 2011 grand finals, with the Penrith Panthers to mark the thirtieth anniversary of their first ever premiership win when they host the Raiders – the team they defeated to win that title in 1991 – at the newly-named Bluebet Stadium. Manly, which won the 2011 premiership, will look to kick-start their struggling season against the team they defeated to win that title, the Warriors, on the Central Coast.
