We could really do with bringing in a veteran CB. We have a very young roster of CB's, and people like Rojo, Bailly and Smalling we hardly lack physical aggressive defenders. I feel like we could do with someone who while lacking the pace and youth, could bring much needed calm and organisation to the defence when required, and be a good partner to our other options. Looks like we could be needing Blind at LB on a regular basis anyway.
Could be a relatively cheap stop gap option that still strengthens the squad rather than just adding another body.
