Arsenal have been plotting a swoop for Doucoure.
The Gunners are planning a huge summer revamp this summer after missing out on Champions League football.
But Palace boss Patrick Vieira has made Doucoure ‘his summer transfer window priority’ as he looks to continue improving his team, says the Telegraph.
The Frenchman, who spent nine years playing at Arsenal, wants to build on his impressive first season in charge at Selhurst Park with another statute addition.
He has known Doucoure for several years since his time in charge of Nice.
