Crystal Palace have agreed a deal of approximately £3.45m with Lille for left-back Pape Souare, according to sources in France.
Get French Football say an agreement has been made of 4.6m euros for the Senegal international, who is currently featuring in the African Cup of Nations tournament.
Souare has played in the Europa League this season with Lille and is understood to offer a threat going forward. The 24-year-old also starred at the 2012 Olympic Games.
If the deal is announced, it ends a yearly-long wait for Palace to land a left-back of Premier League quality.
Souare could fly to London to complete a medical should Senegal reach the knockout stages after tonight's crunch clash with Algeria.
