[FM24||Control Possession; Standard-Setup with Inverted Full-Back!?]

Hello everyone, I'm trying to understand the different game styles better. To do this, I'll start by looking at the standard FM setups. Now a question about the Control Possession: Why is an inverted full-back used? 

Thanks you for your help!

[Maximising Attack and Defence in a Classic 4-3-3]

Hello everyone,
great post. I hope there is a continuation of the article!? I'm a big LFC and Klopp fan. I love the 4-3-3. Especially in the early years under Klopp.
There was a lot more counterattacking going on. After that, the Reds had to increasingly include the ball possession game due to their superiority. 
I am currently training in Argentina for the first time. CA Independiente. There I would also like to introduce a 4-3-3 step by step. Would you choose a half back for the DM position only?
