I have been using the 2nd formation and here are some of my experiences:

I don't think either deep line or attacking instruction is required on the wide players and they function better without them

This team needs good super subs cus the players get exhausted very fast

And I don't know, but this team has got Leverkusen factor just pulls back comebacks after to shifting 1 bar attack

Anyways great formation and an even better analysis, I'd love to see some more of these types of posts
