Some Liverpool fans and players might remember him after Jurgen Klopp's men faced the Germans in a Europa League last season, in which the Premier League side won 1-0 on aggregate.
According to ESPN FC, Liverpool are very close to signing Ragnar Klavan, a centre back from FC Augsburg.
At 6ft 1in, Klavan is a powerful, left-footed player, strong in the air and ranked fourth in terms of clearances per game (5.8) of Bundesliga centre-backs to have made over 20 appearances last season.
Now, that appears to be sorted with the 30-year old providing the German manager with sufficient cover for the mean time with the future of both Andre Wisdom, who failed to impress during a loan spell with Norwich City over the previous campaign, and Lucas, who has been deployed as a makeshift defender on more than one occasion, uncertain.
Klopp, meanwhile, expects Joel Matip to recover from a recurring foot problem sustained during Sunday's friendly win over Wigan Athletic.
"I hope it's only a minor problem", Klopp said.
"The lads who were with us a year ago and are here now know that it is always intensive with Jurgen's training sessions", he said.
Dejan Lovren has praised the performances of his new team-mates and believes an intensive pre-season schedule is helping them to hit the ground running. He's used to it. I think Monday he'll rest, then he can go again.
