We don't have a 'best' CB at the moment. All of them play like they're shitting themselves whenever they're within 5 feet from the ball. Absolutely no difference who plays- Kos, Mustafi, Per, Holding, Chambers, Monreal- all are guaranteed to pull some clownish shit every game.
Signing someone with a positive reputation could shake things up a little. An outsider who hasn't completely lost all confidence in himself and his teammates. Could help us in the short run, as well as the long run obviously, if he's as good as some of you say he is.
