The singer will be know more about one aspect of it yes, but without knowing what you do, I’d imagine that there’s a lot of things that you know about the business that they don’t.
Ultimately, we are talking football. Do the top players have more experience, and interesting anecdotes than someone who spent their career in the Championship? Of course they do. But is there an emphasis placed on dull players who have had PL careers? (usually at a high profile club, the RS got loads of them permeating the airwaves) Definitely.
With regards to their expertise, some of them are genuinely insightful. But not most in my opinion. You only have to look at that video someone has just posted to see all of them On Sky pretty much calling De Bruyne a fairly average midfielder when City bought him. They have big blind spots to other leagues, anyone who seen him for Wolfsburg knew he was the real deal, that wasn’t like City got lucky, they spent £50m on an already quality player.
