Chelsea are considering a deal for free agent Mickael Landreau.
The Daily Star says Chelsea's first signing of the January window could be French goalkeeper Landreau, who is a free agent after leaving Lille earlier this month.
Landreau is a friend of Blues goalkeeping coach Christophe Lollichon and has been offered a six-month contract by the club.
French clubs Nancy, Evian and Bastia are also interested in the 33-year-old, who is close to breaking the all-time record for games played in the French League.
