Just keeping the Sussex lads in Sussex would be a start.
There is a lot to be said for not having to drive your kids 50 miles three times a week for their football. My son is with Cardiff City ADC (PL status irrelevant by the way), my daughter does gymnastics in Bridgend...both require an hour...
As long as we maintain our position, I'm pretty satisfied if we play the long game. Invest in infrastructure, invest in youth development, get as many kids as we can to the stadium lay down a legacy not a quick fix.
I have a feeling this austerity will serve us well in years to come.
