If he is 17-19 M' is ok, don't look at his wage.
If he is 15-16, also he is ft but 2nd class - so you 'll need some extra greens for development.
If he is 15-16 M' but 4*, then he is 1st class ft (and gonna increase his value with higher q).
* don't look at his wage in any of those cases.
that's depends from your stock of greens (and the ability of daily farming).Also, how many tokens should I invest per one of this guys..
You may find a young 18 y.o. ML at 82% q, buy him with 2-3 tokens and then invest 50 greens for AML + 50 greens for Shadow striker + 100 greens for quality and make a fine player for the next 4 seasons.
Auctions for "ready" players with 2-3 positions and sa, go over 50 token.
