Liverpool have been handed yet another injury blow after learning Divock Origi is facing another month on the sidelines.

The Belgium international has been sidelined since he limped off against Leicester City with a hamstrain strain on Boxing Day.

Initially, Origi was ruled out for around three weeks but hopes of a return to action in January have now been dashed.

A Liverpool sources has told Football Insider that the striker has been suffering from a long-standing knee problem and underwent surgery last week in a bid to clear it up completely. Liverpool expect Origi to be out for a further three to four weeks, ruling him out until mid-February.

It’s a blow for boss Jurgen Klopp who is short of firepower at a crucial stage of the campaign.

Danny Ings is out for the season and Daniel Sturridge remains unavailable for selection ahead of Wednesday’s Premier League clash with Arsenal at Anfield.

Klopp is set to choose between Christian Benteke and Roberto Firmino to lead the line against the Gunners.

Liverpool had a staggering 13 players on their casualty list when they took on Exeter in the FA Cup last Friday with a considerably weakened team.

The treatment room is now slightly less congested as Kolo Toure, Jordan Henderson and Mamadou Sakho are set to return for the visit of Arsenal.

Nevertheless, the length of the Liverpool injury list is a huge concern to manager Klopp, who is ready to dip into the January market to strengthen his flagging squad.

As reported by Football Insider, Liverpool have made contact with QPR about taking Steven Caulker on loan for the rest of the season. The centre-back is currently midway through a season-long loan at Southampton but has struggled for game time on the south coast.
