I don't know how you can arrive at this conclusion. Of course we miss Ferno in midfield but he is currently the best fit CB (kids excluded)at the club which says a lot about Otto's form at the minute. Rodri would be a disaster at CB alongside Otto, for starters the lack of pace would be alarming.
What conclusion was it that I arrived at btw?
I don't even mention Fernie playing in midfield or moving back to midfield.
