The All Black back Sonny Bill Williams believes the Warriors can win the National Rugby League title on Sunday.
Williams will line up at second five for the All Blacks in their last Rugby World Cup pool match against Canada in Wellington on Sunday. He'll then watch the Warriors take on Manly in the NRL grand final that night.
Williams, who won a Premiership with the Bulldogs in 2004, says he's been impressed with the Warriors' form the last two weeks.
He says the Warriors forwards are playing unbelievably well and he'll be heading straight off the pitch to watch not only the senior side but the Junior Warriors too, who will try to defend their under-20 title.
There are three Auckland league teams playing grand finals on Sunday with the Vulcans in the New South Wales Cup final as well.
