Wouldn't you want to go to a club which has the least players in your position? And at the moment that is the Clones. We only have defenders. Need at least a couple more.
Can also go 3 CBs, 2 DMs, LM/RM, CAM. It's not often you hear that described as a 3-2-2-1-1. Point still stands though, you can play with 3 backs.
That's not a 5-3-2, that's a 3-2-3-2 variation. DM is Defensive Midfield, I wonder what position that is...
All depends on how you're educated on it tbh. Go have a look on FM, WB's and DM's play on the same line.
