No they didn't do a good job but there we go Vish company law says directors must look after the interests of shareholders. The truth is we have had poor owners for decades which is why we are where we are
So the route cause of all this is Moores selling to the wrong people. We can blame FSG all we want for not building a new stadium but if Moores had done his home work and not sold to H&G (I'm sure there will have been a way not to), we may not be in this situation.
I am no fan of moores yes probably was the root cause selling to Gillet and hicks was a foul up. But that does not make FSG good owners they are stable and professional you can say that but there it ends. They are minimising investment both the team and the stadium in order to lever the maximum return when they sell which hopefully will be soon.
Maybe there are better owners out there but they're hardly minimising spending really. We've been the fifth highest for net spend on players up until this season and are in the top seven for spending (gross) in Europe for the last 7 years. You can say that it's all from player sales but they said we'd be self sufficient and we are.
They've also updated the stadium which no one has done since Moores all those years ago. Maybe not risking all their wealth (why would anyone?) on a new stadium but that's not the be all and end all that you make out as others with shiney new stadiums have proved.
I'd say there are plenty of fans of other clubs that wish they had owners as bad as ours.
