At some point in the next 10 years, I can see the Premier league and bigger teams wanting something more like the NFL's model, where they have more of an ownership over the streaming and get to keep ALL of the revenue. For now, hawking out packages to a few streamers and cable TV companies brings in a lot of revenue, but at some point they're going to want the benefit of having a direct relationship with customers.
I doubt they will EVER have 'watch all of purely your team's games for £x but I can certainly see a 'watch everything' package and various bundles. Just think of that lovely regular direct debit / card transaction money going straight to the premier league. And they can market it globally, directly. All the opportunities to upsell. Charging more for certain games and all that. And all wrapped up in a single Premier League app.
A wise move for apple would be to get in early, and become the partner to achieve this.
