If you are happy to accept we will always be a second tier (at best) club but with no major money worries to trouble us then I guess Tan is the man for you. I have no doubt he is an honourable man and I don't think he would ever abandon us to the fate that befell us under prior administrations.
However, I think by now it should be plain for all to see that he has limited ambition (and know-how) for any long term progression in the club's status. It seems that he is happy to accept unexpected positive outcomes (like the last promotion) but without planning or funding for it.
Yes his main concern might be to keep the club on an even keel but his price for that is that we shall forever be a club lacking the necessary funding and structure to compete at the highest level. I'm absolutely certain his strategy is to get the club into a saleable situation as soon as possible so that he can sever ties with a project which has not fulfilled his ambitions for it.
As ever, and understandably, as it's probably an issue of personalities, some will be grateful we still have a club at all and others will be forever disappointed because that most fundamental hope in football for bigger and better things has been taken away.
