The stadium should not be restricting cash flow for transfers - this isn't a Woolwich situation where the bank pulled out and they had major financing issues. The annual loan payback for the £400m line of credit should be covered by new sponsorships and match day revenue associated with the stadium alone.
That being said, our current cash flow is based on last season, so dividends from the new stadium won't start hitting our transfer spend until next year. But, with the increased revenue from Wembley, CL money as well as new and increased sponsorships from AIA/Nike, there should be more than enough cash for Levy to make signings this summer/in the next 27.5 hours.
TLDR: The stadium is not an excuse for not spending money in the window, either on new players or contract extensions for existing ones.
