Invest LOTS of money in token to pull extra youth each week and getting their reports inmediately.
Searching extra youth using G and waiting 5-8 weeks to get a report is a waste of time and resources right now.
First of all you're talking about spending real money for a game, almost like a slot machine.
Second if you promote youngster then you'll have to train them.
Promotion of players requires a very expansive accademy and that's not quick/easy for a new team finding almost 20 millions for having a the best accademy before spending a lot of real money 40/60 € each season.
Third if you have youngster then you'll have to train them and you'll need training facilities. It's not quick/easy for a new team finding more than 20 millions for having a very good training ground and fitness facility.
Fourth you should need more expansive trainer (at least a 700 thousands G each if not a 120 credits).
After all of this you could find that your budget will drop in an heavy way.
No. A new team can't do all of this things.
A new team needs a lot of seasons for all of this, meanwhile it could be better investing G in medium aged and experienced players for not being beated in every match.
Ps: with an accademy at "the best" level a lot of team isn't finding the talented player they're looking for.
