Tips : assign your scout to your "transfer listed" target, get report card only. Check out the possible price to be accepted by his former club then make an over based on the scout estimated price. A club seldom answering your "inquiry bid", most of the answers are "not for sale"...but actually when you do "transfer bid" with reasonable amount of money they will negotiate the price.
Note:
Scout with low "judging player potential" and "judging player ability" can not reveal the estimation price of a scouted player, recommended scout rate above 16 point in judging player potential as well as judging player ability.
