my advice: dont spend to many time and never money on this game. no matter how much you invest, NORDEUS will make up scores...
buying scouts doesnt mean they will perform awesome.
my experience: dont watch matches, and you will win
getting infos from forum can help but it dont have to. check your opponent formation, try to put up a formation that will overrate his midfield possession.
let players play who have better stats instead of highest star rate.
my fav formations are 4-1-3-2 and 3-1-4-2
the rest is up to nordeus and his dices...
