Sonny, have you found 4231 to be your best formation?
I have most the player in your teams, so I could give them a try
It's the best defensively I have found, offensively not so much.
I haven't really found there to be any formation which is great both offensively and defensively at the same time in FIFA 14, the game mechanics are all over the place and the engine ruins a lot of formations.
3 defenders is too exposed, 5 defenders leaves your midfield or attacking options lacking and overrun, so it has to be 4 at the back.
The problem I have is full backs can go crazy at times and only medium attack ones tend to work for me, where I can force them to move up if I see tons of space and switch play manually.
Then you ideally want 2 cdm's 1 isn't enough IMO as one decent pass can cut him out and then the opponent can do a little dash then hit a long ranger into the net, 2 CDM's usually stops this 9 times out of 10.
so 4-2 with 2 medium attack full backs IMO work best so that gives you:
4222, 4231 (either version) and 442 (2)
I tried all of them and IMO 4231 suited me the best, you may find 4222 or 442 (2) more to your liking though.
My motto is not allowing the opposing team to score easily and being clinical in front of goal and creating chances in the danger zone. So my team and formation is focused on tightening up the back more so than being brilliant attacking wise, I therefore have to rely on game skill to score than overpowering their defence.
I have found that 433 due to the 3 forwards really overpowers the defence pulling them apart making it really easy to score but I cannot get on with it personally. I tried it with Brazil and I played a lot better with 4231.
