Have been giving this a go with Villa.
I've just reached the January window having only made one addition to the default 11.3 Villa Squad (signed Senijad Ibricic for the DLP role, though Bannan has made continued improvements in training and has actually been starting more often at this point).
The tactic has worked very well for creating the desired possession and is brilliant offensively, cheers to that.
However, and this is probably like 90% on my personnel, I've found it to be extremely leaky on the defensive end, particularly against top competition. I really want to chalk that up to Collins/Clark being particularly useless leaving Dunne as my lone solid centreback.
Anyway, for results thus far, we went undefeated in the group stages of the Europa League against AZ, Sampdoria, and one other random Eastern European squad.
Domestically, we did record a pretty impressive 3-0 home win against Man City, and a 2-0 win at Anfield, but we did get smoked by Chelsea (5-0), Man U (3-0), Arsenal (3-0), Tottenham (3-0), and blegh, Sunderland (6-1). 20 games total, we've scored 35 and conceded 35. 11 wins, 8 losses, and 1 draw.
We appear to be particularly leaky away from home. At home we have 7 wins, 2 losses, and 1 draw, scoring 22, and conceding 12. Away from home we have 4 wins and 6 losses, scoring just 13, and conceding 23.
Any suggestions on what to tweak away from home (other than the switch to Standard)?
