This is the way I see it. While we've had lots of not-very-good managers since Tan took over, the buck stops there and with the board he has appointed. It's a club being run by people he trusts with money, not people he trusts to make the right footballing decisions. The result has been years of terrible transfers that have cost a fortune that has not been close to being recovered when players leave (usually on frees), a merry-go-round of managers with their own ideas and styles, being expected to work on bargain buys with no idea of what we want to achieve in terms of playing style, while there's a desire to get back to the money pot of the Premier League but no idea how to get there, other than get lucky with a good manager. Tan has wasted a lot of money on his own stupidity.
I think we all agree that this situation hasn't just happened overnight. Until Tan learns how to run a football club properly, we'll keep being plunged into these problems. What if we somehow stay up this season, what will Tan have learned? Nothing. We'll be back in the same situation next season, unless we get very lucky.
Let's be frank, here. We're set for season after season of struggle at the foot of the table, with dwindling crowds, the way the club is run. Tan will not learn from his previous mistakes and will think, every season, we can make the playoffs. Every season, we'll fail. When Warnock took over, we at least had a decent enough squad, albeit badly managed by Trollope, that had come close to the playoffs the season before. Our current situation is unrecognisable from that.
At the moment we could get relegated this season, or hope for someone to save us this season, then get relegated next season, or the season afterwards. Sorry if that sounds grim, but anyone thinking that "as long as we can survive this season, we can push on next season" needs help. Yes, someone might save us this season, but Tan won't learn and we'll be plunged back into disaster with another shit managerial appointment next summer and the whole thing goes again.
I see us having 2 options:
1) Tan sells up
2) Tan learns how to run the club properly
Otherwise it's back to League 1 and the Football League trophy (whatever it's called) eventually. From there is anyone's guess.
