Real Madrid have been alerted to David Luiz’s fall-out with Chelsea head coach Antonio Conte as the European champions draw up their January transfer plans.

Zinedine Zidane has admitted Real could be in the market for players during the January window and the name of David Luiz has been discussed as a potential defensive target.

The centre-back fell out with Conte after the Champions League draw with Roma at Stamford Bridge, when he was ticked off for his reaction to being substituted.

There were further problems between the pair following the 3-0 defeat in Rome after which Conte conducted a fiery dressing-room inquest.

David Luiz trained alone and was subsequently dropped from the squad for the visit of Manchester United after being perceived to question Conte’s tactics and he also sat out the victory over West Bromwich Albion and the draw with Liverpool, despite being recalled for the Champions League victory over Qarabag last week.

Conte claimed that a knee injury will prevent the defender facing Swansea City at Stamford Bridge on Wednesday night and doubts remain over the 30-year-old’s future at the club.
