4141 low block attacking. Super simplified PI with only tackle harder added
Changes: No overlap on the right side; 2 SS -> 2 AMC at; DLP def -> DLP sup

It goes even better on premier (it can be a normal variation, tho). Still won league 2 crawley town (prediction 24); Achieve 3° place with rushall olympic (prediction 24)
A 41221 attacking. Has won premier easily with solid defense and a good attack. I run a LLM year with crowley town (24th prediction on league 2) and It won two times.
I might test it out if nobody else gets around to it by then
Based on 424 deformation AM4
Changes: Very defensive mentality; WBR: support.

The idea is to see how the tactics work on a very defensive mentality (and thus, lower intensity) mantaining a strutucred team fluidity (thats why the WBR change). I choose to maintain WBL on attack to allow deep runs on ofensive end.
Based on 424 deformation II
Changes: Very defensive mentality; WBR: support, WBL: Support

The idea is to see how the tactics work on a very defensive mentality (and thus, lower intensity) mantaining a flexible team fluidity (thats why the WBR and WBL changes).

Won all championships, except the UCL
Update with Real Madrid LaLiga results. For some reason, AI coach didnt play courtouis as GK, choosing play the inferior Kepa that was loaded from chelsea. This results in some bad games, like the crushing defeat to Milan in UCL, after winning 5-1 at home. It has won all others cups, anyway.
A tweak from 424 deformation. Just swap left AF for a Left AMC Shadow strike, put a hard tackle on him and it is good, just plug and play. It has won the premier, UCL, Carabao and supercup
