Real Betis haven't ruled out re-signing Sunderland midfielder Alfred N'Diaye.
The Frenchman has no future at Sunderland despite an encouraging loan spell with Real Betis last term.
Betis' sporting director Alexis Trujillo said: "N'Diaye had great features and we are not ruling anything out.
"Everything could happen and if N'Diaye is alive he has an option to go to Betis."
