Liverpool manager Jurgen Klopp has explained why he failed to sign a centre-half after the Reds missed out on Virgil van Dijk. The Reds were heavily linked with a move for the Dutch defender – however they ended their interest after Southampton threatened to report them for making an allegedly illegal approach for the player. Defence was Liverpool’s Achilles heel last season; and their defensive woes continued after they shipped in five goals last weekend to Manchester City, after Sadio Mane’s sending off, and let a goal lead slip against Sevilla in the Champions League. However, Jurgen Klopp was adamant that he could not find the right alternative to Van Dijk and insisted that the players he watched would not have improved his side.
