Jamie Carragher explains what Liverpool must do in January window if they are to win Premier League title

Jamie Carragher has explained what Liverpool must do in the January transfer window to give themselves the best chance of winning this season's Premier League title.

Jurgen Klopp's side currently sit three points ahead of second-place Aston Villa in the title race after they recorded a hard-fought victory over Newcastle.

Goals from Mohamed Salah [2], Curtis Jones and Cody Gakpo sealed the 4-2 win at Anfield but for many, Monday's clash also highlighted their vulnerability in defensive areas.

Liverpool are currently without their two first-choice left-backs, Andy Robertson and Kostas Tsimikas.

And last month, experienced centre-back Joel Matip was ruled out for the remainder of the season after suffering an ACL injury in their clash against Fulham.

After Monday night's full-time whistle, Sky pundit Gary Neville said Liverpool should be looking to make moves in the January window to help strengthen their title challenge.

And moments later, Jamie Carragher went one step further by suggesting they need to bring another defender as they head into the second-half of the season.

"You can’t help but look at this Liverpool team and compare it to the team that won the league. It’s not as good as that team, that was unbelievable team but you then look at the facts," he told Sky Sports.

"This is a team who from the end of last season to right now, have lost one Premier League game in 30. That is unbelievable for any team. Maybe I need to start giving this team more credit and respect.

"But I still feel Manchester City have got the edge and are still favourites for the title right now."

Carragher added: "On the back of the two injuries to the left-backs and Joel Matip being out for the season, I think the position they find themselves in is it is an opportunity they can’t waste.

"I do feel Liverpool have to bring a defender to the club in January. Liverpool have got something Arsenal haven’t got which is a manager who has won the title before.

"And players within that squad who are genuinely world class players. When you are talking about the other challengers whether that is Arsenal or Aston Villa, they are still yet to prove that."
