4-5-1v... Well I use defensive, down both flanks, mixed, CA on, low press, normal tackle, man marking, OT off. Up arrows on the fullbacks and wingers, and down arrow on the DMC. The DMC is the most important player on the pitch; he has significant contribution to both the defence and midfield. With this formation, your main goalscoring roots are usually the setpieces, especially CKs. The high Q players for this formation are the wing players and the DMC. Unfortunately I have not won a single match this season, but then, I've got some a new set of players, with the old faithful (John, Bircan, Baert... They are not old, just played a lot of games at the club) gone. Keeper has been out of form. I need just one win... One win can bring the team back.
OK, the squad can consist of a full 22-man roster, or these:
1 GK
3 of each DL/DC and DC/DR
1-2 DMC (he can be a DC/DMC too... I suggest multi-position players)
3 MC [or 2 MC and 1 DMC/MC (he's your sub)]
1 of each AML/ML, AMR/MR, AML/AMC/AMR (this is your sub)
1-2 ST
The bottom line — a keeper, 6 defenders, 2 DMCs, 3 MCs, 3 attacking midfielders and 2 ST. 17 players can do the job; you may add another keeper but it's usually not needed.
