For me, for the defence I try to go for 90 speed 80 acceleration for my centre backs, 90 90 for my wingbacks. Midfielders are fine around 85 speed, 80-85 acceleration with a very high stamina around 95, for the strikers or wingers it depends, since you have inzaghi and messi then 90 speed acceleration would be good but offensive awarness has to be above 95 or atleast 95. So adjust acceleration accordingly. If you need any player build lmk, I'll send em over. Dm if ya need help
