I was scrolling up and down at Transfermarkt.co.uk to get some official transfer news for teams around Europe (as much I care for any of them because i get info about them only at transfermarkt), and then when I had nothing else to do I found myself staring at Chelsea squad in the season 2013-2014.
Somehow I found myself stuck at the Squad of FC Chelsea U21 in the season 2013-2014 and figured out that they (transfermarkts' dudes) considered the possibility of giving a market value to our lesser-known prospects outside Chelsea's fanbase world. And look what they got tiil now:
Jamal Blackman - 175.000 £ 200.000 €
Nathan Ake - 1.300.000 £ 1.500.000 €
Cristian Cuevas - 1.500.000 £ 1.700.000 €
Kenneth Omeruo - 875.000 £ 1.000.000 €
Ruben Loftus-Cheek - 125.000 £ 150.000 €
John Swift - 225.000 £ 250.000 €
Lewis Baker - 225.000 £ 250.000 €
Islam Feruz - 625.000 £ 700.000 €
Nathaniel Chalobah - 3.500.000 £ 4.000.000 €
Wallace - 1.800.000 £ 2.000.000
While you can find those values somehow way too short of your thinking you probably need to consider that the notable thing to consider is that they at least got considered after successful Next-Gen campaign. Some others even don't got mentioned.
So if we agree to those market values how much value you consider should be given to those others that aren't on that list (Bertrand Traore, Jeremie Boga, Charly Musonda Jr, Alex Kiwomya, Andreas Christensen, Alex Davey, Josimar Quintero, Kyle Scott, Isaiah Brown, Josh Aina, Kevin Wright, George Brady etc.)?
