As Ive said (edited)... ratings, only show you the way in what a player works, lets say "type of player".
These types can be, key player (8-9-10)+goals and assistances, near 1 per match at least of one of these 2 things,, between 6-7-8 that can, contribute, maybe some match a MC in defense , or at least 1 goal/assistance in 2 matches, + some MoM... or do not contribute despite 8-8-8-8-8.... and low rated players, that usually, do not contribute (only exceptions).
Always is the same, home-away-attend-or not, what say all about a player, are the stats (MC-ST) and for defense and GK take a look at MoM, is good to have defenders that obtain these + live matches you can see if they fail or not, + if a MC work in defense.
So my answer basically is, no, but at same time yes. lol
