The stadium is the real key to Usmanov financing Everton. As it stands right now, we make money from gate receipts at Goodison. That money goes towards revenue and towards FFP, but obviously isnt much. A new stadium is expensive when it comes to cash outlay, but its expenses dont count against FFP.
So as the new stadium project goes forward, we not only gain much higher matchday revenue that go straight towards FFP, but Usmanov can now sponsor, at say 30 million per year, the stadium itself. The stadium allows us(through Usmanov) to go an extra +40 million per season in spending.
There are only three ways to get around FFP: increasing matchday, merchandising, and sponsorship revenue. We cant do too much about merchandising yet, but we can greatly increase matchday and sponsorships.
