We sometimes put Demi as a defensive midfielder, usually late in games to shore up. I was wondering about the flexibility of the CBs?
I know there were discussions in the past, that when Hughes bought VK from Hamburg he could play in CB and midfield.
For what its worth on Transmarkt:
Otamendi is shown as being able to play either left or right CB and as a secondary position right back.
VK and Demi are both shown as being able to play either left or right CB and as a secondary defensive midfielder.
Denayer is shown as being able to play either left or right CB with no secondary position.
