Chelsea boss Jose Mourinho values Belgium playmaker Eden Hazard at £200m after reported interest from Real Madrid.
Alan Pardew is weighing up chasing a big-name summer signing to boost Crystal Palace's profile.
Bastia have announced the signing of free agent goalkeeper Mickael Landreau on a deal until the end of the season.
The 33-year-old was out of contract after leaving Lille by mutual consent on December 6 following an apparent falling-out with general manager Frederic Paquet.
Landreau, who began his career at Nantes before joining Paris St Germain, spent three years at Lille, winning the league and cup double in 2011, and was under contract until 2014.
The France international will officially join Bastia on December 31.
Speaking in the wake of his departure from Lille earlier this month, Landreau said: "The most important thing is to blossom on the pitch. I could not anymore. And a year and a half is a long way to go when you have hard days.
"I have freed myself both sportingly and psychologically."
Landreau could make his debut for his new club in their Coupe de France derby encounter with Championnat National side CA Bastia on January 6.
