If you bought those players for 10-100k, why I couldn't have done the same for training purposes?
Of course you could. Everybody could. But it was at the beginning of season. Now, you have to pay more.

Do you know how much costed steel 2 years ago? Of course, you could have bought steel then...but if you haven't and you need steel now, you have to pay X times more. Market. Try to persuade sellers now that steel isn't worth such much because 2 years ago costed X times less
