I bought a player yesterday
(13194877) with a DMI of 3,657,900 but today his DMI is showing as 1,042,000.
None of his skills nor his game shape have changed and he hasn't aged.
So, what else influences DMI? Something to do with the quality of league the player plays in?
I know from playing Hattrick that the equivalent there (TSI) is meaningless in itself, but losing 72% of DMI in one day is rather alarming..! :S
