It’s no secret that Liverpool need to strengthen in defence.
Liverpool have one of the best attacks in Europe, but their defence is not quite at the same level.
In two games against Manchester City and Tottenham they conceded nine goals, showing why they are still lagging behind Pep Guardiola’s league leaders.
Strengthening mid-season could see them get back into the title race, after they failed to add new centre-backs in the summer.
Here is a look at three potential options for January…
Virgil van Dijk

Yes, the obvious choice, but he has to be mentioned. Liverpool made Virgil van Dijk their top target in the summer, but bungled their pursuit.
Van Dijk was keen on a move too, but Southampton have previously stated they have no intention to sell.
Jonathan Tah

Bayer Leverkusen defender Jonathan Tah has emerged as one of Germany’s brightest prospects.
The 21-year-old is a regular for the Bundesliga side and has already racked up more than 100 first team appearances.
Matija Nastasic

Former Manchester City defender Matija Nastasic looked a top prospect under Roberto Mancini.
He is now playing for Schalke in the Bundesliga, who he joined in 2015.
The Serbian international’s Premier League experience makes him an even more viable candidate for a move, and at 24, his best years are ahead of him.
