Chelsea are watching Nabil Fekir's situation at Lyon.
Sport says Chelsea could move for Liverpool target Fekir if Eden Hazard leaves for Real Madrid.
Lyon playmaker Fekir is one of the Blues' preferred options.
Following Liverpool's £67m purchase of goalkeeper Alisson from Roma, the Reds are not expected to return for Fekir now the World Cup is over.
Mexico international Hirving Lozano, of PSV Eindhoven, also has admirers at Stamford Bridge.
Fekir and Lozano would cost around the same figure at £63m, and either player would apparently join if an acceptable offer was made by Chelsea.
