Chelsea could become the latest club to join the race for Celtic right-back Josip Juranovic - who impressed for Croatia at this winter's World Cup.
The Stamford Bridge club are seeking right-back reinforcement after Reece James suffered an injury during their win over Bournemouth on Tuesday.
England star James is set to be sidelined for up to four weeks, having missed the World Cup through damage to the same knee.
Chelsea are considering their options, with Juranovic among the names believed to have been discussed ahead of the January window opening.
