Look, its simple
The 3-5-2 has proven to be an exceptionally solid, durable team.
We need a 3man backline and wingbacks, as we and the azzurri have proven its the only way you can put a massive organisation currently, with 4-2-3-1 beeing the exception but that needs exceptionally good players.
So there you have it, we need the 3-5-2. We can consider going 3-4-1-2 once pogba is a permanent starter.
But stop these retarded 4 man backline formations. they dont work for us
