Former Liverpool defender Andrea Dossena has urged the Reds to go all out in their attempts to sign Napoli centre-back Kalidou Koulibaly.
The defender has been persistently linked with a move away from Naples in recent weeks, and a host of European sides have been linked with a swoop for Koulibaly.
Speaking to Radio Musica TV, Dossena said: "If the league resumes, Napoli will struggle to qualify for the Champions League, so they will have to sell some important players.
"Klopp is missing one piece to complete a stratospheric squad and the Koulibaly-Van Dijk pairing could become a big barrier. Liverpool have no economic problems and therefore a deal with the English club would be within reach."
