Former Liverpool and Napoli defender Andrea Dossena has urged Jurgen Klopp to sign centre back Kalidou Koulibaly this summer.
Koulibaly has become one of the most sought after defenders in world football after shining in Serie A for Napoli, attracting interest from the likes of Liverpool, Manchester United, Barcelona and PSG.
The centre back produced two good performances against Liverpool in the Champions League this season and Dossena believes signing Koulibaly would be the final piece of the Reds' puzzle.
Speaking to Radio Musica TV, Dossena - who played for Liverpool between 2008-2010 - said he thinks Napoli should let Koulibaly go if they don't qualify for next season's Champions League.
