Neither here nor there. That said you're ignoring the fact that be it Kane, Winks, Mason, Bentaleb, Andros, KWP, Onomah, Carrol, Skipp, Caulker, Livermore.... We've kicked out a decent stream of HG players that have contributed on the pitch and/or financially speaking.
Whether players make the starting XI or are sold they're still contributing to the bigger picture.
Whether it achieves that particular goal of helping us avoid the HG market or not, us investing in the academy is not a stick to beat us with.
