A few month ago I've tried to find full players ID list but there were only fragmentary parts so I decided to do it myself. It was enormously hard work but with help from NaFer I finished this list. Now you can download it in xml. format. The list accommodates players from FIFA 04-10, EURO 2012 and 2008, FIFA World Cup 2010 and 2006, UEFA Champions League 2006-07 and some players from FIFA 2000-2003 and 2011-13. I didn't add evry player from last versions of the game because you can find them on sofifa.com resourse.
So here's the list. Enjoy it! All credits to NaFeR

P.S. some players have two or more ID's - I've tried to find them all and mark with the numbers in a small column. Also I marked FAKE players and players with FAKE ID's from UEFA EURO 2012. Also some ID's vere linked to the different players. I've tried to find such ID's and show possible variants - the main (which was used in the latest versions) and others, from earlier versions. Some players haven't ID numbers cos I was not able to find them - only the proper place.
