I agree that he is a great CB. I don't know if he would be a automatic starter, but has the ability to be the best CB in the world. He is also a threat from set pieces.
Chelsea to bid for Benatia. Hope we go for him, but not sure if he would want to fight for a starting place. http://www.soccernews.com/chelsea-bid-benatia/146267/
It will be a shame if he leaves, but I think £40m is too good to turn down.
