Canterbury have won just one game from four to start the season with several Bulldogs legends calling for Hasler’s head.

The mentor is off contract this year. 

Experts believe the methods which brought the coach early success, including two grand finals in his first three years at Belmore, are not working anymore.

Tolman disagrees.  

"I don't think he needs to change,” he said. “Obviously we need to improve a few things from last week. I suppose that's where you'll see the change.”

"But in terms of our footy structures, I don't think that really needs to change too much."

Tolman said the players still had belief in Hasler’s approach.

"That's the question that's always going to be asked, but at the end of the day it was our performance on the weekend that cost us the game. Des wasn't out there," he said.

"Since I've been here, even though we've been in every finals series in the past five years and two grand finals, there's always been pressure.

"At the moment we're (1-3) and we're not going to great, so that pressure builds a bit. But we've got full support here from Des and moving forward that's the way it's going to continue."

Greg Eastwood agreed. 

"The board and CEO decide (on his job). For now, Des has our full support and we're right behind him. We've been to six finals in the last six years he's been here. He's got the right formula."
