Yup we definitely do look weak ish at the back, an injury to VVD or Konate and will struggle. Having the best attack is futile if you're suspect at the back. I'd want us to focus on buying a CB for now. Then we could revisit Isak if Nunez is sold. If we were to miss out on Isak, Nunez stays and we sign a quality CB. I'd be somewhat satisfied.
Ideal world you want Isak in, Nunez out and a CB in but I don't think that will happen.
