Martin Skrtel's replacement is undergoing a medical at Liverpool ahead of a £4.2m move
Defender Ragnar Klavan's medical at Liverpool is under way ahead of his £4.2million move from Augsburg.
The vastly-experienced Estonia international has been brought in as cover at centre-back as Mamadou Sakho and Joe Gomez both currently have injuries and Tiago Ilori, who could have been a fall-back option, is heading to the Olympics with Portugal.
Klavan has over 100 caps for his country and has had four seasons in the Bundesliga and manager Jurgen Klopp sees him as the ideal man to offer back-up and leadership in much the same way as Kolo Toure did before his departure this summer.
Press Association Sport understands a deal for Klavan is likely to be concluded on Wednesday.
Klopp's new first-choice centre-back for the coming season Joel Matip escaped serious injury to his ankle in Sunday's friendly win at Wigan.
The Cameroon international, a free transfer signing from Schalke, sustained bruising to the joint and while he is unlikely to play in Wednesday's friendly at Huddersfield he will be on the flight to the United States the following morning as the club's tour of America begins.
Goalkeeper Adam Bogdan is also unlikely to play against Huddersfield as he is set to complete a loan move to Wigan.
Klopp will come up against his long-time friend - and best man at his wedding - David Wagner at the John Smith's Stadium in the club's penultimate domestic friendly (they will play Barcelona at Wembley on their return from the States).
"We worked for a few years together," the German told liverpoolfc.com.
"He was my coach of our Under-23 side with Borussia Dortmund. He is an experienced manager and has done a really good job up until now.
"He made a big impact, I heard, when he went to Huddersfield. It changed a lot and that's really good.
"I know a few (Huddersfield) players because they have brought in a few German players and I managed two of them in the past. They are a really good team, for sure, and it's a good challenge for us.
"Playing against a Championship team in a pre-season game is really difficult because they are really hot.
"They are greedy, they are ambitious and sometimes, maybe sometimes, it's one of the best games in their whole year - so no big pressure and only opportunity.
"We have a long day on Wednesday because we fly to the USA after the game for our tour.
"It's not easy for us but at the end of the day I want difficult situations in the pre-season."
