Reds boss Jurgen Klopp watched his side fail to score a goal for the third game in a row, as the champions drew 0-0 with Premier League leaders Manchester United. Meanwhile, former Liverpool striker Ian Rush believes Jurgen Klopp doesn't have to buy a replacement for Virgil Van Dijk during the January transfer window. Liverpool have been operating with a makeshift centre-back pairing since losing Van Dijk and Joe Gomez to long-term injuries with midfielders Jordan Henderson and Fabinho playing at the back. Rush told that finding the right defender could prove problematic and is backing Klopp if he chooses not to sign any cover before the end of the window.
