Ragnar Klavan is closing in on a move to Liverpool from Augsburg, with his medical pencilled in for Tuesday.
The seasoned centre-back is due to have his physical check before wrapping up the paperwork on a deal in the region of £4 million plus add-ons.
An official announcement on his transfer is expected on Wednesday should proceedings go as planned.
The Estonia captain will become Liverpool's fifth permanent signing - the third recruited from the Bundesliga - under Jurgen Klopp's management.
Klavan will provide defensive cover with Mamadou Sakho and Joe Gomez sidelined for the start of the season.
The duo are undertaking a sensitive loading program to recover from tendinopathy of the Achilles, and the 30-year-old will effectively serve as Kolo Toure’s replacement.
He possesses an abundance of experience having earned more than a century of international caps, as well as more than 100 appearances each in Germany's top-flight and the Eredivisie.
Liverpool, meanwhile, are in negotiations with Newcastle over midfielder Georginio Wijnaldum.
Rafael Benitez's side want to bank the most sizeable fee possible for the Dutch international, placing an initial value of £27m on him, but the Reds are hoping to do business nearer to £20m as they seek a quick deal.
