Playing three at the back, I do think that Sakho, Lovren and Matip is likely to be superior to a trio including Klavan. In fact, that's a pretty imposing back three. Even with a CB pairing, when we consider how much one of either Lovren or Matip has been injured causing us to play Klavan or Lucas, the Sakho situation has clearly cost us. Indeed, there's a few points gone in that decision. Obviously, it looks like there is no way back, but we should have used him whilst he was our player.
