Figured I would come back to this with how got on, have 3 games left of the season but have now won the league. Final tactic, there's a few PI's as well:
Results following the loss in inital post:
Some big gaps in the fixtures in December and January so did do some friendlies against small teams to keep fitness up for the restart. Champions League didn't go well drew 2, lost 4. One of the draws I was 3-0 up..
Tactic has had some tweaks along the way and the TF(A) does change, but is always an attack duty. Support duty means the AP gets too crowded out. On a few occasions the strikers weren't playing well at all and I ended up with a 4321 shape instead. Roko Simic was on 22 goals and 9 assists before a 6-9 month injury which was just before the 0-0 with LASK and it threw me off. After that though another striker (Konate) decided to finally turn up and score some goals.
Scored some really nice goals, more in line with what I was expecting to begin with. During the big break I actually bothered with some real squad planning and training setups and let some players leave. Ultimately I think the Salzburg team isn't as strong as previous years (as seen IRL) and maybe I expected too much from them. But at the same time think the tactical tweaks did help.
