Cameron Smith believes a confident and happy Shaun Johnson will be a huge danger for Australia in Sunday's Four Nations clash against New Zealand in Coventry.
Johnson proved to the be the difference in the Kiwis' 17-16 win over England last week, scoring a try and kicking the winning field goal in a fine all-round display.
The mercurial Warriors playmaker was poor in the recent loss to the Kangaroos in Perth, criticised heavily for his fifth tackle options as David Kidwell's side lost 20-6.
However, he rediscovered his mojo against the hosts at Huddersfield and Smith said making his life difficult on the pitch will be a vital part of his team's gameplan.
"It will be everybody's job to stop him," Smith said.
