Celtic look set to sign QPR defender Steven Caulker, who has worked with Brendan Rodgers previously, on a free transfer.

The 25-year-old Englishman has played for Southampton, Liverpool and Tottenham, and would bring valuable Premier League experience to Celtic having made over 200 career appearances, 123 of which have come in the English top flight.

The Championship side are willing to offload Caulker on a free transfer having paid £8 million for him in 2014, but will look to insert a sell-on clause in the deal with the Hoops according to West London Sport.

Negotiations have been ongoing between both parties and it is understood a deal is close to being agreed for the defender who worked with the Celtic manager at Swansea.

Following the injury to Dedryck Boyata, Caulker could come into the side alongside Jozo Simunovic with Erik Svitachenko’s overall game becoming less suited to Rodgers’ style.

QPR are looking to get Caulker off their wage bill as he is one of the club’s highest earners, and left him in London having gone on their pre-season tour.

Rodgers has already added three players this summer, and may soon add a fourth to bolster his options in defence.

Caulker recently admitted to alcohol and gambling addiction, as well as mental health problems – but could be set for a fresh start north of the border with the chance to play in the Champions League.
