Daryl Gibson is "100 per cent" confident there's no player-driven plot to oust him from the struggling NSW Waratahs Super Rugby franchise.
The Waratahs coach wouldn't comment on "unsubstantiated rumours or whispers" when asked about a Fairfax report on Monday that claimed he had lost the support of a number of unnamed players, saying he hadn't felt the need to ask the players if they had any problems with him."
Dean Mumm, meanwhile, backed Gibson and the Waratahs coaches, saying the onus must be on the players in a disappointing Super Rugby campaign.
The retiring Waratahs and Wallabies lock, who played his last home appearance for NSW in the 40-27 mauling by the Jaguares in Sydney on Saturday said the players had to take responsibility for the poor campaign and they "absolutely, without a doubt" believed in the coaching panel headed by Gibson.
"I think from the top down we're very happy with what's going on and a lot of the onus of that comes back to the players."
Mumm had no doubt the Waratahs were a good team, with good players.
"I don't doubt what we can do as a team when we get things right, we just don't get it right often enough."
The increasing pressure on Gibson comes just weeks after Waratahs chief executive Andrew Hore said in announcing a coaching reshuffle that the New Zealander was "the right man to lead the organisation" in making necessary changes.
The reshuffle of the Waratahs backroom will see Cam Blades leave and Australia Under-20 and Northern Suburbs coach Simon Cron move into an assistant role under Gibson, while defence coach Nathan Grey will end his work with the Waratahs to join the Wallabies full-time under Michael Cheika.
The changes for the Waratahs come as a result of an internal review of roles and responsibilities which Hore said had identified areas where the Waratahs must improve -- including coaching, physical conditioning, leadership and player responsibility.
"We're initiating changes to ensure we have great talent coming through the ranks and we'll continue to put systems in place to provide the best environment for our team to be successful," Hore said.
