I have used thousands of formations and the truth of the matter is, top eleven still remains work in progress in terms of giving the WIN to the person playing a good formations.
I have lost to this formation too many times with less stars.
NO striker

Something like this. So if you have the quality players, the better formation clearly ; whats the reason to why someone would loose not one...two ..or three....6 matches or more to someone with a formation that is un heard of in real life. Common now...its all money for top eleven.
