It looks really effective, also a good option to find a versatile formation. Thank you for sharing it.

I am also thinking about using the 3241 or the 4141 as a basic because these seems versatile as well.

At the moment I am level 3, so far from having a decent team, however trying to get the appropriate players for each positions. As you mentioned the best if a player can cover multiple, relevant posititions without a substitution.

Right now I am focusing on wing plays with 1 ST and a decent defense. however its not effective all the time against stronger enemies. Its still in the process to find out what would be the best defense/counter formation against much stronger opponents.
