Liverpool are believed to be trying to push through Steven Caulker’s loan move in time for him to be available for Wednesday’s visit of Arsenal.
It is understood the QPR centre-back, who has been on loan at Southampton, has returned to Loftus Road to thrash out a short-term deal – subject to a medical – for him to move to Anfield.
Reds officials are trying to complete the paperwork before the midday deadline in order to register the 24-year-old so he is eligible to go straight into the squad should he be required.
Any medical would then have to be done on Merseyside and with the players training late this afternoon there is even the possibility Caulker could link up with his new team-mates at Melwood today.
Caulker has made only one Premier League start and two substitute appearances this term and his lack of action has alerted several clubs, but Liverpool are leading the race to sign the former Cardiff man.
Southampton, Queens Park Rangers and Caulker would all have to agree to cancel his current loan for him to move elsewhere this month as there is not believed to be a get-out clause in the contract.
Crystal Palace and Bournemouth are also believed to be tracking Cauker, who signed for QPR for £8million from Cardiff in July 2014.
QPR are likely to demand around £5million to allow Caulker to leave permanently if an agreement can also be struck with Southampton to end his loan early.
Jurgen Klopp is desperate to strengthen his defence with Martin Skrtel, Kolo Toure, Mamadou Sakho and Dejan Lovren all on the sidelines through injury.
Sakho and Toure are close to returning to action, but Klopp is believed to be keen on a new defender after he was forced to play Jose Enrique and Tiago Ilori in central defence in the FA Cup draw at Exeter.
Caulker has made 120 Premier League appearances for for Tottenham, QPR, Swansea, Cardiff and Southampton since making his bow in the top flight in 2012 for Spurs.
It is also not the first time Caulker, whose last game was Southampton’s 6-1 drubbing by Liverpool, has been targeted by the Reds as he was also wanted by former boss Brendan Rodgers.
