Chelsea boss Jose Mourinho will have to find a replacement if he sells David Luiz.

Sport says Barcelona are ready to move for Luiz, who joined Chelsea from Benfica for £25m in January 2011.

If Chelsea sell him they will inherit the problem of how to replace him. Mourinho likes Eliaquim Mangala but Porto have made it clear they want more than £35m for the 22-year-old French international.
