It was a rapprochement of sorts between Williams and the NRL club, who fell out bitterly after Williams left the club to play rugby union in France in the middle of the 2008 season.
The team of the decade was named last night in Sydney, at a dinner to celebrate the club's 80th anniversary.
Williams is in the back row alongside his former captain, Andrew Ryan, and New Zealand test enforcer Greg Eastwood.
Hazem El Masri, Michael Ennis and current skipper James Graham are also some of the names in the team, which was selected by a panel including rugby league historians Ian Heads and David Middleton and former premiership-winning Bulldogs coach Phil Gould.
