In game form. any advice

[nikolgiorgos]

well @jwoods if you expect a dev to come here and give you advice how to handle the rates of your players during a game, you 'll wait for a looong time.
Actually it's a forum for users, to share their experiences.
So, let me give you some tips.

I use most of the times 4-5-1 V so it's about these positions I can help.
GK - doesn't matter the rates.
GK just reflects the flow/ calculations/ RNG of the game so nothing you can do about it.
If your GK has bad rates for 4-5 games in continuance, then something is wrong and better replace/ sub him.

Defenders - Also doesn't matter the rates.
Just if you see that oppo has too many shots, switch to man to man, hard tackling, high pressing
If you see that some defender has a yellow card in first 30' and has a bad rate, sub him ( second yellow is waiting for him ).
Don't sub a defender after (about) 55-60' , no matter his bad rate. you 'll concede a goal.

DMC is a key player. If he has under 6,5 sub him

MC aren't key players. Doesn't matter the rate. not bellow from 6-6,5 is ok.
Those are ok players to made a sub.
You must do one sub in every game. Better round 65'.
You get an extra green and a possible goal.

AMR-AML are key players. Must have 7,5 and above. If lower, then make a sub.
(the same with a AMC player).

ST isn't a key player. Doesn't matter the rate.
Unless you use him as a F-K or penalty kicker.

If your kicker/specialist, has a low rate, he has a "bad" day and you must remove him manually (during the game) from your first choice.

Well its clearly what to do when 1 player are in bad form. But what to do when whole defense or whole midfield turns in red?
