When you sign up you get an email that say funds are split as follows:
FIRST TEAM
Directly supporting the Football Management Team’s budget by investing in the
recruitment, development and retention of top talent to allow us to continue to compete
and win at the highest levels.
YOUTH ACADEMY
Enhancing the AFC Youth Academy’s ability to identify, recruit, develop and inspire local
young talent by creating experiences which will prepare young players for first team football.
CREATING A HIGH-PERFORMANCE ENVIRONMENT
To create a best-in-class Football Medicine, Sports Science and Performance Analysis
support structure for all professional and Youth Academy players, ensuring they are
as well equipped as they can be.
As you can see it is quite woolly and definitely not a guarantee that money is going to first team only.
Edit: could even argue that last bit opens door for funds to be diverted to Kingsford.
