No, we dont. Like every position in the team its about the other players on the pitch. Having Smalling, one of the best out and out defenders in the league relieves some of the pressure on other players to be at the top defensively - our fullbacks, his partner at CB, our midfield. In return they are the ones who need to be good on the ball and make things happen. Imagine saying you cant win with Ronaldo on the wing because he doesn't track back as much as other players. People did say that actually when he was younger and it was just as silly as suggesting you can't win a title with your best defending CB.
