Real Betis are on the verge of making a £5million-plus profit on the sale of Sunderland old boy Alfred N'Diaye.
Midfielder N'Diaye moved to Spanish side Betis two years ago in a deal worth around £1million after then Sunderland boss Gus Poyet opted to offload the Senegal international.
Poyet took charge at Betis this summer and is going to offload N'Diaye for a second time, although this sale will be for big money.
Betis are understood to have agreed a fee of around £6.5m with fellow La Liga outfit Villarreal for the 26-year-old.
That's twice as much as the £3m Sunderland originally paid for N'Diaye in January 2013 after Martin O'Neill brought in the powerful midfielder.
Successor Paolo Di Canio didn't rate N'Diaye and sanctioned his loan exit after just six months at the Stadium of Light, before Poyet rubber-stamped his permanent departure.
