I think your expectations from an owner is unrealistic. Every owner of any company in the world want to grow their brand as much as possible, so the return they receive will be higher. What's wrong with that?
It's in FSG best interest for us to be successful.
Exactly as Vish says return on investment and FSG may calculate league title or even champions league will not meet their risk / return threshold especially with spurs strengthening. Look at this season Liverpool finished seventh went out of both cups early on but anfield a sell out every week and club able to increase ticket prices by ten per cent
From FSGs point of view why change anything?
