With regards to Michael Keane, I wouldn't want him to start over Nelson.
However, in terms of our squad, is he actually a better defender than both Coady and Faes?.. I actually think he might be! (Which speaks volumes as to how poor i feel Faes has been!).
If we are to go into the Championship season with Nelson, Souttar, Okoli, Vestergaard and Keane, as our center back options, that's really no that bad, and will arguably represent the best combined options for CB in the division.
