Clive Churchill Medallist Willie Mason has predicted a winning dynasty for the Bulldogs after they claimed their first title since 1995.

Mason is one of several key players of Sunday's premiership outfit who will be off-contract at the end of next season.

The towering forward showed why the 'Dogs can't afford to lose him as he constantly made in-roads into the Sydney Roosters' defensive line in a thrilling 16-13 grand final victory at Telstra Stadium.

"The next contract I do will be to set my life up so I'm going to be looking for the best deal possible for me," said Mason, before joking he would retire following Sunday's win.

"I want to build a dynasty here. There's ten class players here.

"You'll probably see tomorrow when they pick the Kangaroos side how many get in."

Mason has blossomed into a genuine leader at the club since last year's Kangaroos tour of New Zealand and Great Britain.

"This year I've worked really hard and I want respect when I walk into rep sides," said Mason.

"Maybe some people think I shouldn't have deserved it but this year I can hold my head up high and if I do get picked in sides I'll try my best."

It hasn't been easy for the 24-year-old Mason, who's been dogged by controversy in 2004.
