The Premier League giants have reached a pre-contract agreement with the Schalke centre-back Joel Matip.
The 24-year-old defender is out of contract in the summer and will join the Reds as a free agent.
Klopp is understood to be an admirer of the strong and athletic centre back and according to Italian media, a deal is in place to bring him to Anfield.
Liverpool have struggled with their defence over the last few seasons and Klopp is looking to address his back four right away.
Adding someone like Matip will give the Reds some much-needed strength and aerial presence at the back.
