Liverpool on Thursday announced they had completed the £40-million ($55 million) signing of Bournemouth defender Milos Kerkez.
The 21-year-old, who has penned a five-year deal, is the third major signing of the transfer window for the Premier League champions following the arrival of Jeremie Frimpong and Florian Wirtz.
Germany midfielder Wirtz was signed for a club-record fee that could reportedly rise to £116 million.
