The 24-year-old central defender initially moved to Southampton on loan in the summer of 2015 and was scheduled to remain at the Premier League side until the end of the season. However, that agreement has been cancelled, and Caulker has joined Liverpool.
Klopp has explained why he decided to move for the centre-back, who started this professional club career at Tottenham Hotspur before switching to Cardiff City in the summer of 2013.
“We looked for Premier League experience because in this short time, you need that experience,” Klopp told Liverpool’s official website. “We looked for a good header [of the ball] because that’s what we need – we want to play good pressing, we want to press the opponent and so they have to play long balls.
“If they play long balls, you need people in the last line who can help you with headers. And we’ve found it with Steven Caulker.
During his loan spell at Southampton, Caulker could feature in only three Premier League games. The Englishman created one chance, had a pass accuracy of 73%, and won three headers and two tackles.
Liverpool are eighth in the Premier League table at the moment with 30 points from 20 matches. The Merseyside outfit are six points behind Tottenham Hotspur, who are currently fourth and occupy the final Champions League spot.
