This player seems to underscore, more than anything, the lack of understanding most users have of an appropriate training regimen. Players with high JS and JR while having mediocre skills everywhere else are all over the transfer list. These players don't perform to the level their salary would dictate and when you add in the pitiful stamina, it's no wonder the prices for these types of players is very low.
As a new user, I'm fine with the long time advancement takes. Training is still valuable for team improvement and the transfer prices for balanced, well-trained players are still relatively high.
