I would say budget for finishing 10th, and anything above that is a bonus, we have learned the hard way with the John Boyle years the dangers of reckless spending.
A top 6 finish and a European place and / or a decent cup run are the targets for 10 of the 12 premiership clubs every year, and to be honest given the standard outwith the ugly sisters you don't need to spend big to achieve those targets.
We are a well run, and seemingly financially stable club at the moment so I hope it stays that way.
