Only reason any team plays 3 centre halfs is if the defenders arent good enough to play as a 2. Batth might make all the difference to him and allow us to attack more
Well, that's not true, there are loads of tactical reasons as to why you might play three at the back.
If you have creative players who are perfectly suited to playing as wing-backs, you might accommodate them; you might want to play three through the middle and also have two up top.
