#3 Centre-back: Diego Carlos
Liverpool are reportedly in talks with Sevilla over the potential transfer of Diego Carlos to Anfield next summer.
The Merseyside giants boast of an incredible defence but a series of injuries this season have left Klopp fearing the worst as they hope to lift their first Premier League title at the end of the season.
Joe Gomez, Dejan Lovren and Joel Matip have all been injured this season, and if a crisis arises, there are hardly any options to deputise in the centre-back position.
As a result, Liverpool could look to step up their chase for Carlos, and bring him to Anfield this month. He could serve as a suitable partner to Virgil van Dijk, and could even pose as a threat during set-pieces, having scored twice in 20 appearances in all competitions this season.
The Brazilian has a £64 million release clause in his contract with Sevilla, but Liverpool need to act fast as Real Madrid are also believed to be interested in the 26-year-old as he is being viewed as an ideal long-term replacement to Sergio Ramos.
