Just wait for them to announce the main sponsor, I'm sure I read they cancelled last year's earlier than planned.Newcastle have just signed a 7.5m sleeve sponsor deal. (Our main shirt sponsor is only 10m). Their sleeve sponsor is partly owned by their owners.
Bearing in mind a sleeve sponsor is usually about 20% of the main.... 37.5m a year from Saudia Airlines? Neom? Saudi Tourism? (beautiful, by the way)
Other clubs can whine about fair value, but the bar is already set. In 18 months their revenues will be right up there.
