You can't fault his commitment. He means well and I think he is / was desperate to succeed here. It is clear he was badly advised to begin with and whatever his links are to Doyen / Paixao they haven't helped the club progress. It is pretty evident he did not take FFP into account in his first few seasons here and was banking on a Wolves style quick promotion.
I would say after working in Thailand on and off for nearly a decade, being married to a Thai and also briefly meeting DC and having an informal chat with him and my wife he does exhibit a common trait of people in this country. There is a huge hierarchical system here and people at the very top find it almost impossible to listen or take on advice from somebody who they would deem inferior to them. It isn't an arrogance, but it seems he hasn't adapted his way of working to a football context. I very much doubt he is willing to admit fault and cause himself to lose face with his failings here. Although, this may well turn out to be positive for SWFC in a sense that he will be desperate to make a success of his ownership rather than walking away having failed.
