The trouble with using the media, and the threat of leaving, to negotiate your position, whether its for money or power, is that eventually the owners will accept the resignation.
I think this was eventually the case with Clough at Derby where he had threatened to throw toys out again, and was probably surprised when the chairman accepted. I'm not sure the Liebherr's will continually cave in to 'demands'. What they choose to do if NC walks is of course the worry.
