Some managers specialize in predicting player's sub-levels and buying the ones that are very close to the next level. They try to make that player pop in just 1 training and then selling him for a good profit. These people are known as skill traders There are several tools that can help in predicting sub-levels, but it is said that the expertise and experience of the manager is the best tool available. This is not to be confused with daytrading, for skill traders actually field players or buy players that played on the right position that week with their former club so they get training at their new club. lam biến đánh tieng viet que' de bua neo sieng minh dich ra cho
