So how much is normal? Is training 1 skill level normal? Or maybe 2? Or is it normal to spend 5 season training each player before you sell them?
It's another topic of discussion...
no thats the question for this topic, if you just train one or two skills, you sell him fast after buying it, with profit.
Actually, as long as it is not possible to make extremely large profits, this type of trading is an expected feature of the transfer market. So you're wrong.
How much money do you think is a "extremely large profits"? 2 million in a season isn't extremely large? I saw managers with this numbers.
Really with high cost players? I traded a bit with minute fillers(guys i bought for 1k for the friendly), and i got 14 transfers and just get 70% of the sum of them. So if you buy and good player you need to make, 42% profit after making a few transfer to sell them with +/- 0.
With cheap player you could easily makes 5-10* of the buying sum, so it could work with them, but i don't know how it works with normal transfer when you make masses of them, because i would say that it was with me a +/- thing when i was going to sell a trainee with 2% extra fee next season for 5 Million then i have to make large profit with mickey mouse transfer in the past.
