In FM2018, the 4-4-2 formation is very powerful.
Inverted winger and Carrillero are wonderful chance makers.
ML and MR switch each other.
STL and STR switch each other.
I strongly recommend that you use this against 1 striker tactics.
When you face the teams with 2 strikers tactic, I recommend using my other FM18 tactic: Suk Sam 5-2-3 (3 strikers).
Team training : Balance-average (but adjust 'low' when there are 2 or more matches in one week)
pre-match prep. : Let your assistant handle it.
Individual trainings : adjust them by the injury susceptibility. (as same roll they do)
Corner kicks : MCR or MCL
Some tweaks including 'drop deeper' 'offside trap' and individual instructions to reduce goals conceded.

It works very well with 18.1 patch.I tested this with West Brom.
