how can such a good player be worth so little? I mean, the prices in this game doesn't follow how real life pricing is in football.
Young talents cost as much as older players who have managed to become superb
Price means that player SHOULD progress faster with normal training THAN cheaper or older player.
In 20 cases +70-80% will be like that, but you may get player which makes average progress in training. VICE VERSA applies too.
