I won't bum you. You make a good point that our academy will be discouraged by this.
All I can say is that I understand why Txiki would do it if he thinks Sane is Ballon d'Or level potential. Probability wise, it's unlikely we have that type potential at the academy. Even the best academies can't produce those players consistently.
It's also possible we created the academy with the idea that we wouldn't develop any great talents for six or seven years, and in the meantime use it to generate extra revenue. The prices for domestic players in the Premier League are absolutely mad right now with the influx of money. Naismith for 9m, for instance. And he's not even homegrown. I know what we say in the press, it's just hard to reconcile that with our purchasing behavior. Seems we look at our academy first, but we do so ruthlessly. If a player doesn't have the potential to be world class, we have no problem spunking fortunes young talents.
Very possible this is a demand by Guardiola.
