Stoke City full-back Glen Johnson is on a list of possible January signings at Barcelona and the former England international will have the backing of his old Liverpool team-mate Luis Suarez.
The Catalans have a major crisis at right-back where the £16m signing of Aleix Vidal has been a disaster.
The 27-year-old was bought last year as Dani Alves’ eventual replacement but problems over attitude and tactical adaptation have left him on the sidelines permanently even when Barca have had an injury crisis in his position.
Manager Luis Enrique has taken to converting midfielder Sergio Roberto to right-back on a permanent basis and using a back three or Javier Mascherano in times of emergency.
