This is a great experiment for computer vs computer simulations. When I played FIFA, I tried to buy cheap players with properties that worked well with my playing abilities. For me, at least until FIFA14 (did not try beyond that), a player's speed had the most net positive in my scoring ability and I used to buy the fastest yet cheaper players instead of buying a really skilled but slow players[1].
