Please tell me what the advantage of an all star game is, North vs South, ?
The Premier League is coming under increasing pressure to come under government regulation and give more money to the football pyramid. That's going to get much worse in the next 9 months because of the energy crisis lower league teams literally can't keep the lights on and some will go bankrupt.
Boehly's idea to use it to generate money for the pyramid is clever because it becomes a massive, very visible thing for the Premier League to point to as benefitting lower league clubs while actually committing very little money (£200m+ of new money takes nothing away from the clubs) while also serving their own expansion plans.
They'd probably host it around the world, they'd use it to sell the league and keep themselves ahead of everyone else. The London NFL games have shown that these pilot events are really good drivers of bringing in new fans, that's why Baseball and the NBA has copied them. So that's the advantage for the owners.
For fans, it's no less interesting than the Audi Cup or Emirates Trophy in preseason.
