I am to be fair.
The best tactic is 442 with full backs and CMs both staying back when attacking. Spam firm passes into strikers feet.
I watched some pro or streamer talking about it (aye, one of them fannies). I tried it last night, I'm division 5 and I was winning games comfortably by three or four goals and promptly got promoted into div 4 and got £20,000 for it.
Now whether it was the actual tactic or just in my head is a different matter but it felt like I was cruising games.
