Sky Sports understands that Premier League clubs are considering an approach for Lille forward Salomon Kalou.
Table-topping Arsenal and title hopefuls Liverpool are both believed to be keeping a close eye on his situation.
Were they to make a move, they would be getting a man who knows all about English football.
Kalou spent six years at Chelsea between 2006 and 2012 - netting 60 goals for the club.
He has been linked with a return to England ever since he took the decision to head for France on a free transfer.
January 2014 could see him make such a move, with interest in his services mounting.
