The club can look at it two ways.
On the one hand the new stadium will attract a lot of season ticket sales because its new, so we needn't (or can't) spend too much on new players.
On the other hand any new found fans attracted by the new stadium will not renew in year two if the product on the field isn't good enough.
I think we need one big signing for next year*, one to get the town buzzing, it will be a wasted opportunity if the new stadium draws in first time fans then we let them drift away.
*but I'm not holding my breath
