hmmm.. Funny how differently people play the game, not a criticism just an observation. things i look for when buying a player are:-
>Stats corresponding to what position they play e.g, defenders need to have good tackling pref 16 and above for
prem.
>Avrg rating of season so far above 7.20 im happy with.
Cant say ive noticed the bottom right one to often, but id say current ability, think this is a rating out of 200, so that example is ok if say your are a championship side i would guess.
Hope ive helped in some way dude.
