Perhaps it was coded " good CB's v "better CB'.
Warnock is a clever old owl , he maybe protecting himself , if maybe aware of someone leaving like Connolly wanting to go , big bid in for Manga /Morrison we could not turn down .
This lad maybe be a good full back cover or defensive midfielder ,bring them all in I say .
If Bamba got sent off and Manga was injured or away on int duty , that center back pool doesn't look that strong to me and lacks a enough good ball carriers or pace.
