If you don't like the price don't sign him. Simple?

Management game is about making decisions. Decisions can be good or bad, good managers learn from their mistakes and get better. Bad managers can put a lot of money into the game and still failed to win the trophies he wanted.

But I can tell you, if you know how to manage your team, the token costing youth is one of the better option available. Unlike transfer market, he cost no money and is risk-free to sign, and is always a fast trainer, that can keep 5* quality relatively cheap until age 26. That is with a few green pack spending you can keep a 4~5* for 8 seasons, and he will worth a lot to sell when you don't need him, way more than the wage and bonus you paid during the time he played in your team.

Anyway, since these options are also offered to other managers I don't see any problem about it. Sign him or not is your choice, nobody forced you to pay anything.
