I listen to some advice but not all.
I think he get a bad reputation because he kind of comes in after bonuses and what not. I often play games where I have 15+10=25% possession bonus over my opponents that can be 2-3 stars. Sometimes I take a lead of like 5-0 in the first half and have 70/30 possession, and AM comes in and say that we cannot get possession of the ball...
If anyone have any spare time it would be good to rip all advice in English and put in a thread and start discussing them one by one. I often only have a vague recollection of what they say.
What I never listen to is "Our attackers need more support", I play mostly with one attacker. What I give up in one area, I gain in another. Against better teams, it could possibly have a negative impact if I went with two attackers.
The "We need to be more aggressive" thing is what it is. The AM won't save you if you get a red card or a PS....
I never change my approch when he say that I should (defensive/normal/attacking and so forth).
I think most of the other can be pretty useful. I always focus passing when he recommends that. If he tells you to turn off your off-side trap, its a good advice.
