Using a 442 which I have found to be pretty decent this year with a classic big man, little man front two and a destroyer and more attacking CM in the centre of midfield. Mandzukic and my untradable Javier Hernandez are going well. Have been promoted from Division 9 to Division 5 in consecutive season with three different 442 teams and looking good for Division 4.
In the cups, been using a 433(5) which is again decent this year. My untradable Mata is by far my top scorer and assister in Fifa 17 so far. Have modified that team to be all BPL from untradables and random non rares I have stashed in my club for the current FUT Champions Qualifier and am in the semi final with two tries left.
Have been looking to use discard IF's again and my 442 has IF Paletta at CB who is pretty decent. Also been using IF Iago Falque in the false 9 team before it was changed to BPL for the tournament.
I'm keeping games played, goals assists and cards stats for every single player I'm selling so by the end of FUT 17 I'll be able to account for every single player I've used at all!
