I think we will buy a CB in this window, we were a CB down after losing Lovren.
Under normal circumstances Fab would have been adequate cover, but after the loss of VVD, Gomez and Matip (will always miss games) we are short. I think Klopp was hoping the youngsters would be able to cover, and at first they looked like a solution and have done us proud.
I personally don't want to see Rhys, Billy and Nat playing the majority of the games, they are a year or so off (which is totally understandable)
