I think that you’ve confused being good for his age and having a lot of potential with being established as being one of the best players in Europe.
What Sterling has over Palmer isn’t just experience, it’s his development to become what Palmer might be, one day if all our dreams come true.
Indeed, if Palmer were as good as Sterling, now and at his age, then he’d be worth £150M+ and the biggest clubs in Europe would be queuing up to tempt him away from us.
I’d love to see him make it, I truly hope he does, but you need to separate dreams and best wishes from reality.
