He won't sell if we go down, too much of a loss. He might sell should we stay up but would do well to get his money back.
I'd imagine Tottenhams revenue streams to be much higher than ours so off the field we'd need success to allow commercial revenue and gate reciepts to grow - success will mean extra investment and suddenly we're back to square one.
Tottenhams strategy seems to have been hire an astute Manager and get a decent scouting network together, add in the extra invetment and the London factor and Bobs your uncle - you finish erm 5th or 6th.
Our strategy appears to be a general cost cut, reduce players wage bill, bosmans, promote youth players, go about managerial recruitment in a lazy hap hazard way and then hope to stay up.
Tottenhams and our strategies are similar on one respect though - the mindset comes from the top.
