Was trawling through the EA forums for some inspiration and came across a 352 thread, I actually like the formation but it's difficult to use so end up binning it after a while, I thought things couldn't be much worse with consistency so I'd give it a shot. This is my current team, everyone is on 10 chem apart from Bale who is on 8.
It's fun to use, it's rare you have a bank of 5 at the back but the wingers do get back, it just depends on how attacking your opposition is. Ronaldo at CAM has brought out the best in him too, just makes great runs, he has 28 in 34 but his record before this formation wasn't great at all.
It's not the formation to use if you're just bothered about winning, it's easily exploited by a good player but it's definitely competitive and you will score a shed load (also conceding a shed load)
Had to skimp on some players unfortunately, Neto is meh but needs must.
