Finances, cup competition success and always winning the league are suspicious. It's not one success, or one event, but the whole picture.
If you look at my signings, they are capable of this. I'm playing with a slightly changed Goals Galore tactic there.
4-3-3 - No wingers
GK - Defend
FB - Support - General CB - General CB - FB - Suppot
Box-To-Box Mid - Ball Winning Midfielder - CM Automatic
Adv. ST - Poacher - Adv. ST
I change the midfield and forward positions to suit my players but I always have a poacher and that is usually my main goalscorer.
I have no idea how to proof this but.. it's your choice as a person to make your own decisions.
PS: I'm just going to take these accuses of cheating as a compliment.
