Largely depends on age? Seriously just how stupid are you? If that were the case then Rashford would command a larger market fee than Kane. Talent is the predominate factor, always has been, always will be. That determines the primary value of a player - to think otherwise demonstrates an extraordinary level of ignorance. Levy has had it wrong all these years - he just needed to sign a group of 20 year olds and we would have been title winners.
As for Juventus well yes they did just like when they spent £75 million on a 28 year Higuain who had little to no commercial value. Just like when they spent a world record fee for a defender in 2001 for Thuram who was 29 or when they paid one of the highest fees at the time for Nedved who was also 29. But hey you just focus on spelling I’ll just continue to bury you in own your stupidity and ignorance.
Don’t be obtuse. Who is worth more - a 25 year old Harry Kane or a 33 year old Harry Kane? All other things being equal, age is a significant factor, and if you can’t see that then you’re thicker than I gave you credit for. Amazing I know.
