No, that's just how some modern football clubs operate, including us. The likes of Bayern and Liverpool would never be in this position - it's a take it or leave it from them. There's no way academy players hold those clubs to ranson. Bartomeu has destroyed the wage structure and it's only natural to expect that every player passing through sees what is around him and acts accordingly. If you play for a club where the top stars are earning a fairly acceptable salary and you know how the pecking order goes, you will act as per the circumstances. In a world where Bumtiti and Greizman are on astronomical salaries, you look at that and go like hey, why should I not earn more?
Let's not confuse inflation in salaries and transfer prices with shitty wage structures and running of the club.
